General Usage

Basic

• Currently recommended TF version is tensorflow==2.10.0. Expecially for training or TFLite conversion.
• Default import will not specific these while using them in READMEs.

  import os
  import sys
  import tensorflow as tf
  import numpy as np
  import pandas as pd
  import matplotlib.pyplot as plt
  from tensorflow import keras
  

• Install as pip package. kecam is a short alias name of this package. Note: the pip package kecam doesn't set any requirement, make sure either Tensorflow or PyTorch installed before hand.

  pip install -U keras-cv-attention-models
  # Or
  pip install -U kecam
  # Or
  pip install -U git+https://github.com/leondgarse/keras_cv_attention_models
  

  Refer to each sub directory for detail usage.
• Basic model prediction

  from keras_cv_attention_models import volo
  mm = volo.VOLO_d1(pretrained="imagenet")
  
  """ Run predict """
  import tensorflow as tf
  from tensorflow import keras
  from skimage.data import chelsea
  img = chelsea() # Chelsea the cat
  imm = keras.applications.imagenet_utils.preprocess_input(img, mode='torch')
  pred = mm(tf.expand_dims(tf.image.resize(imm, mm.input_shape[1:3]), 0)).numpy()
  pred = tf.nn.softmax(pred).numpy()  # If classifier activation is not softmax
  print(keras.applications.imagenet_utils.decode_predictions(pred)[0])
  # [('n02124075', 'Egyptian_cat', 0.9692954),
  #  ('n02123045', 'tabby', 0.020203391),
  #  ('n02123159', 'tiger_cat', 0.006867502),
  #  ('n02127052', 'lynx', 0.00017674894),
  #  ('n02123597', 'Siamese_cat', 4.9493494e-05)]
  

  Or just use model preset preprocess_input and decode_predictions

  from keras_cv_attention_models import coatnet
  from skimage.data import chelsea
  mm = coatnet.CoAtNet0()
  preds = mm(mm.preprocess_input(chelsea()))
  print(mm.decode_predictions(preds))
  # [[('n02124075', 'Egyptian_cat', 0.9653769), ('n02123159', 'tiger_cat', 0.018427467), ...]
  

• num_classes={custom output classes} others than 1000 or 0 will just skip loading the header Dense layer weights. As model.load_weights(weight_file, by_name=True, skip_mismatch=True) is used for loading weights.

  from keras_cv_attention_models import swin_transformer_v2
  
  mm = swin_transformer_v2.SwinTransformerV2Tiny_window8(num_classes=64)
  # >>>> Load pretrained from: ~/.keras/models/swin_transformer_v2_tiny_window8_256_imagenet.h5
  # WARNING:tensorflow:Skipping loading weights for layer #601 (named predictions) due to mismatch in shape for weight predictions/kernel:0. Weight expects shape (768, 64). Received saved weight with shape (768, 1000)
  # WARNING:tensorflow:Skipping loading weights for layer #601 (named predictions) due to mismatch in shape for weight predictions/bias:0. Weight expects shape (64,). Received saved weight with shape (1000,)
  

• num_classes=0 set for excluding model top GlobalAveragePooling2D + Dense layers.

  from keras_cv_attention_models import resnest
  mm = resnest.ResNest50(num_classes=0)
  print(mm.output_shape)
  # (None, 7, 7, 2048)
  

• Reload own model weights by set pretrained="xxx.h5". Better than calling model.load_weights directly, if reloading model with different input_shape and with weights shape not matching.

  import os
  from keras_cv_attention_models import coatnet
  pretrained = os.path.expanduser('~/.keras/models/coatnet0_224_imagenet.h5')
  mm = coatnet.CoAtNet1(input_shape=(384, 384, 3), pretrained=pretrained)  # No sense, just showing usage
  

• Alias name kecam can be used instead of keras_cv_attention_models. It's __init__.py only with one line from keras_cv_attention_models import *.

  import kecam
  mm = kecam.yolor.YOLOR_CSP()
  imm = kecam.test_images.dog_cat()
  preds = mm(mm.preprocess_input(imm))
  bboxs, lables, confidences = mm.decode_predictions(preds)[0]
  kecam.coco.show_image_with_bboxes(imm, bboxs, lables, confidences)
  

• Calculate flops method from TF 2.0 Feature: Flops calculation #32809.

  from keras_cv_attention_models import coatnet, resnest, model_surgery
  
  model_surgery.get_flops(coatnet.CoAtNet0())
  # >>>> FLOPs: 4,221,908,559, GFLOPs: 4.2219G
  model_surgery.get_flops(resnest.ResNest50())
  # >>>> FLOPs: 5,378,399,992, GFLOPs: 5.3784G
  

• tensorflow_addons is not imported by default. While reloading model depending on GroupNormalization like MobileViTV2 from h5 directly, needs to import tensorflow_addons manually first.

  import tensorflow_addons as tfa
  
  model_path = os.path.expanduser('~/.keras/models/mobilevit_v2_050_256_imagenet.h5')
  mm = keras.models.load_model(model_path)
  

• Code format is using line-length=160:

  find ./* -name "*.py" | grep -v __init__ | grep -v setup.py | xargs -I {} black -l 160 {}
  

Layers

• attention_layers is __init__.py only, which imports core layers defined in model architectures. Like RelativePositionalEmbedding from botnet, outlook_attention from volo, and many other Positional Embedding Layers / Attention Blocks.

from keras_cv_attention_models import attention_layers
aa = attention_layers.RelativePositionalEmbedding()
print(f"{aa(tf.ones([1, 4, 14, 16, 256])).shape = }")
# aa(tf.ones([1, 4, 14, 16, 256])).shape = TensorShape([1, 4, 14, 16, 14, 16])

Model surgery

• model_surgery including functions used to change model parameters after built.

from keras_cv_attention_models import model_surgery
mm = keras.applications.ResNet50()  # Trainable params: 25,583,592

# Replace all ReLU with PReLU. Trainable params: 25,606,312
mm = model_surgery.replace_ReLU(mm, target_activation='PReLU')

# Fuse conv and batch_norm layers. Trainable params: 25,553,192
mm = model_surgery.convert_to_fused_conv_bn_model(mm)

ImageNet training and evaluating

• ImageNet contains more detail usage and some comparing results.
• Init Imagenet dataset using tensorflow_datasets #9.
• For custom dataset, custom_dataset_script.py can be used creating a json format file, which can be used as --data_name xxx.json for training, detail usage can be found in Custom recognition dataset.
• Another method creating custom dataset is using tfds.load, refer Writing custom datasets and Creating private tensorflow_datasets from tfds #48 by @Medicmind.
• Running an AWS Sagemaker estimator job using keras_cv_attention_models can be found in AWS Sagemaker script example by @Medicmind.
• aotnet.AotNet50 default parameters set is a typical ResNet50 architecture with Conv2D use_bias=False and padding like PyTorch.
• Default parameters for train_script.py is like A3 configuration from ResNet strikes back: An improved training procedure in timm with batch_size=256, input_shape=(160, 160).

  # `antialias` is default enabled for resize, can be turned off be set `--disable_antialias`.
  CUDA_VISIBLE_DEVICES='0' TF_XLA_FLAGS="--tf_xla_auto_jit=2" ./train_script.py --seed 0 -s aotnet50
  

  # Evaluation using input_shape (224, 224).
  # `antialias` usage should be same with training.
  CUDA_VISIBLE_DEVICES='1' ./eval_script.py -m aotnet50_epoch_103_val_acc_0.7674.h5 -i 224 --central_crop 0.95
  # >>>> Accuracy top1: 0.78466 top5: 0.94088
  

  
• Restore from break point by setting --restore_path and --initial_epoch, and keep other parameters same. restore_path is higher priority than model and additional_model_kwargs, also restore optimizer and loss. initial_epoch is mainly for learning rate scheduler. If not sure where it stopped, check checkpoints/{save_name}_hist.json.

  import json
  with open("checkpoints/aotnet50_hist.json", "r") as ff:
      aa = json.load(ff)
  len(aa['lr'])
  # 41 ==> 41 epochs are finished, initial_epoch is 41 then, restart from epoch 42
  

  CUDA_VISIBLE_DEVICES='0' TF_XLA_FLAGS="--tf_xla_auto_jit=2" ./train_script.py --seed 0 -r checkpoints/aotnet50_latest.h5 -I 41
  # >>>> Restore model from: checkpoints/aotnet50_latest.h5
  # Epoch 42/105
  

• eval_script.py is used for evaluating model accuracy. EfficientNetV2 self tested imagenet accuracy #19 just showing how different parameters affecting model accuracy.

  # evaluating pretrained builtin model
  CUDA_VISIBLE_DEVICES='1' ./eval_script.py -m regnet.RegNetZD8
  # evaluating pretrained timm model
  CUDA_VISIBLE_DEVICES='1' ./eval_script.py -m timm.models.resmlp_12_224 --input_shape 224
  
  # evaluating specific h5 model
  CUDA_VISIBLE_DEVICES='1' ./eval_script.py -m checkpoints/xxx.h5
  # evaluating specific tflite model
  CUDA_VISIBLE_DEVICES='1' ./eval_script.py -m xxx.tflite
  

• Progressive training refer to PDF 2104.00298 EfficientNetV2: Smaller Models and Faster Training. AotNet50 A3 progressive input shapes 96 128 160:

  CUDA_VISIBLE_DEVICES='1' TF_XLA_FLAGS="--tf_xla_auto_jit=2" ./progressive_train_script.py \

• Transfer learning with freeze_backbone or freeze_norm_layers: EfficientNetV2B0 transfer learning on cifar10 testing freezing backbone #55.
• Token label train test on CIFAR10 #57. Currently not working as well as expected. Token label is implementation of Github zihangJiang/TokenLabeling, paper PDF 2104.10858 All Tokens Matter: Token Labeling for Training Better Vision Transformers.

COCO training and evaluating

• Currently still under testing.

• COCO contains more detail usage.

• custom_dataset_script.py can be used creating a json format file, which can be used as --data_name xxx.json for training, detail usage can be found in Custom detection dataset.

• Default parameters for coco_train_script.py is EfficientDetD0 with input_shape=(256, 256, 3), batch_size=64, mosaic_mix_prob=0.5, freeze_backbone_epochs=32, total_epochs=105. Technically, it's any pyramid structure backbone + EfficientDet / YOLOX header / YOLOR header + anchor_free / yolor / efficientdet anchors combination supported.

• Currently 3 types anchors supported, parameter anchors_mode controls which anchor to use, value in ["efficientdet", "anchor_free", "yolor"]. Default None for det_header presets.

  anchors_mode	use_object_scores	num_anchors	anchor_scale	aspect_ratios	num_scales	grid_zero_start
  efficientdet	False	9	4	[1, 2, 0.5]	3	False
  anchor_free	True	1	1	[1]	1	True

  Note: COCO training still under testing, may change parameters and default behaviors. Take the risk if would like help developing.

• coco_eval_script.py is used for evaluating model AP / AR on COCO validation set. It has a dependency pip install pycocotools which is not in package requirements. More usage can be found in COCO Evaluation.

Visualizing

• Visualizing is for visualizing convnet filters or attention map scores.
• make_and_apply_gradcam_heatmap is for Grad-CAM class activation visualization.

  from keras_cv_attention_models import visualizing, test_images, resnest
  mm = resnest.ResNest50()
  img = test_images.dog()
  superimposed_img, heatmap, preds = visualizing.make_and_apply_gradcam_heatmap(mm, img, layer_name="auto")
  

  
• plot_attention_score_maps is model attention score maps visualization.

  from keras_cv_attention_models import visualizing, test_images, botnet
  img = test_images.dog()
  _ = visualizing.plot_attention_score_maps(botnet.BotNetSE33T(), img)
  

  

TFLite Conversion

• Currently TFLite not supporting Conv2D with groups>1 / gelu / tf.image.extract_patches / tf.transpose with len(perm) > 4. Some operations could be supported in tf-nightly version. May try if encountering issue. More discussion can be found Converting a trained keras CV attention model to TFLite #17. Some speed testing results can be found How to speed up inference on a quantized model #44.
• tf.nn.gelu(inputs, approximate=True) activation works for TFLite. Define model with activation="gelu/approximate" or activation="gelu/app" will set approximate=True for gelu. Should better decide before training, or there may be accuracy loss.
• Not supporting VOLO / HaloNet models converting, cause they need a longer tf.transpose perm.
• model_surgery.convert_groups_conv2d_2_split_conv2d converts model Conv2D with groups>1 layers to SplitConv using split -> conv -> concat:

  from keras_cv_attention_models import regnet, model_surgery
  from keras_cv_attention_models.imagenet import eval_func
  
  bb = regnet.RegNetZD32()
  mm = model_surgery.convert_groups_conv2d_2_split_conv2d(bb)  # converts all `Conv2D` using `groups` to `SplitConv2D`
  test_inputs = np.random.uniform(size=[1, *mm.input_shape[1:]])
  print(np.allclose(mm(test_inputs), bb(test_inputs)))
  # True
  
  converter = tf.lite.TFLiteConverter.from_keras_model(mm)
  open(mm.name + ".tflite", "wb").write(converter.convert())
  print(np.allclose(mm(test_inputs), eval_func.TFLiteModelInterf(mm.name + '.tflite')(test_inputs), atol=1e-7))
  # True
  

• model_surgery.convert_gelu_and_extract_patches_for_tflite converts model gelu activation to gelu approximate=True, and tf.image.extract_patches to a Conv2D version:

  from keras_cv_attention_models import cotnet, model_surgery
  from keras_cv_attention_models.imagenet import eval_func
  
  mm = cotnet.CotNetSE50D()
  mm = model_surgery.convert_groups_conv2d_2_split_conv2d(mm)
  mm = model_surgery.convert_gelu_and_extract_patches_for_tflite(mm)
  converter = tf.lite.TFLiteConverter.from_keras_model(mm)
  open(mm.name + ".tflite", "wb").write(converter.convert())
  test_inputs = np.random.uniform(size=[1, *mm.input_shape[1:]])
  print(np.allclose(mm(test_inputs), eval_func.TFLiteModelInterf(mm.name + '.tflite')(test_inputs), atol=1e-7))
  # True
  

• model_surgery.prepare_for_tflite is just a combination of above 2 functions:

  from keras_cv_attention_models import beit, model_surgery
  
  mm = beit.BeitBasePatch16()
  mm = model_surgery.prepare_for_tflite(mm)
  converter = tf.lite.TFLiteConverter.from_keras_model(mm)
  open(mm.name + ".tflite", "wb").write(converter.convert())
  

• Detection models including efficinetdet / yolox / yolor, model can be converted a TFLite format directly. If need DecodePredictions also included in TFLite model, need to set use_static_output=True for DecodePredictions, as TFLite requires a more static output shape. Model output shape will be fixed as [batch, max_output_size, 6]. The last dimension 6 means [bbox_top, bbox_left, bbox_bottom, bbox_right, label_index, confidence], and those valid ones are where confidence > 0.

  """ Init model """
  from keras_cv_attention_models import efficientdet
  model = efficientdet.EfficientDetD0(pretrained="coco")
  
  """ Create a model with DecodePredictions using `use_static_output=True` """
  model.decode_predictions.use_static_output = True
  # parameters like score_threshold / iou_or_sigma can be set another value if needed.
  nn = model.decode_predictions(model.outputs[0], score_threshold=0.5)
  bb = keras.models.Model(model.inputs[0], nn)
  
  """ Convert TFLite """
  converter = tf.lite.TFLiteConverter.from_keras_model(bb)
  open(bb.name + ".tflite", "wb").write(converter.convert())
  
  """ Inference test """

Using PyTorch as backend

• Experimental Keras PyTorch Backend.
• Set os environment export KECAM_BACKEND='torch' to enable this PyTorch backend.
• Currently supports most recognition and detection models except cotnet / halonet / hornet / nat / nfnets / volo. For detection models, still using tf.image.non_max_suppression_with_scores while running prediction.
• Basic model build and prediction.
  • Will load same h5 weights as TF one if available.
  • Note: input_shape will auto fit image data format. Given input_shape=(224, 224, 3) or input_shape=(3, 224, 224), will both set to (3, 224, 224) if channels_first.
  • Note: model is default set to eval mode.

  from keras_cv_attention_models import res_mlp
  mm = res_mlp.ResMLP12()
  # >>>> Load pretrained from: ~/.keras/models/resmlp12_imagenet.h5
  print(f"{mm.input_shape = }")
  # mm.input_shape = [None, 3, 224, 224]
  
  import torch
  print(f"{isinstance(mm, torch.nn.Module) = }")
  # isinstance(mm, torch.nn.Module) = True
  
  # Run prediction
  from skimage.data import chelsea # Chelsea the cat
  print(mm.decode_predictions(mm(mm.preprocess_input(chelsea())))[0])
  # [('n02124075', 'Egyptian_cat', 0.86188155), ('n02123159', 'tiger_cat', 0.05125639), ...]
  

• Export typical PyTorch onnx / pth.

  import torch
  torch.onnx.export(mm, torch.randn(1, 3, *mm.input_shape[2:]), mm.name + ".onnx")
  
  # Or by export_onnx
  mm.export_onnx()
  # Exported onnx: resmlp12.onnx
  
  mm.export_pth()
  # Exported pth: resmlp12.pth
  

• Save weights as h5. This h5 can also be loaded in typical TF backend model. Currently it's only weights without model structure supported.

  mm.save_weights("foo.h5")

Recognition Models

AotNet

• Keras AotNet is just a ResNet / ResNetV2 like framework, that set parameters like attn_types and se_ratio and others, which is used to apply different types attention layer. Works like byoanet / byobnet from timm.
• Default parameters set is a typical ResNet architecture with Conv2D use_bias=False and padding like PyTorch.

from keras_cv_attention_models import aotnet
# Mixing se and outlook and halo and mhsa and cot_attention, 21M parameters.
# 50 is just a picked number that larger than the relative `num_block`.
attn_types = [None, "outlook", ["bot", "halo"] * 50, "cot"],
se_ratio = [0.25, 0, 0, 0],
model = aotnet.AotNet50V2(attn_types=attn_types, se_ratio=se_ratio, stem_type="deep", strides=1)
model.summary()

BEiT

• Keras BEiT includes models from PDF 2106.08254 BEiT: BERT Pre-Training of Image Transformers.
