A simple wrapper for tos

Project description

easy_tos

让数据流动变得简单!Make data flow!

pip install easy_tos==0.7.0 --index-url https://pypi.tuna.tsinghua.edu.cn/simple
# 或者
pip install easy_tos==0.7.0 --index-url https://pypi.org/simple  #清华等其他镜像源可能同步慢

这个库的开发是包含了大部分常用的 tos脚本操作,避免许多重复代码。以及让很多新入职的同事能够快速用起来我们的数据。

准备工作

准备 tosutil config

# 首先在 ~/.bashrc 或者 ~/.zshrc 中 export 自己的 key
export TOS_ACCESS_KEY="YOUR ACCESS KEY"
export TOS_SECRET_KEY="YOUR SECRET KEY"
export TOS_ENDPOINT="https://tos-cn-beijing.ivolces.com"
# 如果是火山引擎内网用 "https://tos-cn-beijing.ivolces.com",
# 如果是本地网用 "https://tos-cn-beijing.volces.com",
export TOS_REGION="cn-beijing"
export TOSUTIL_PATH="~/tosutil"
TOS_CONFIG = {
    'ak': f'{os.environ["TOS_ACCESS_KEY"]}',
    'sk': f'{os.environ["TOS_SECRET_KEY"]}',
    'endpoint': f'{os.environ["TOS_ENDPOINT"]}',
    "region": f"{os.environ["TOS_REGION"]}",
    "tosutil_path": f'{os.environ["TOSUTIL_PATH"]}'
}



场景一:tos 桶内,桶与桶之间,桶和本地之间的数据传输

# 传输文件夹
tosutil cp -r -u -j 96 -p 96 {tos_dir} {local_dir}
tosutil cp -r -u -j 96 -p 96 {local_dir} {tos_dir}
tosutil cp -r -u -j 96 -p 96 {tos_dir} {tos_dir}

# -r : 批量传输文件夹内容
# -u : 表示增量传输,中间中断,下次跑同样命令会在之前的结果上继续传输,而不是从头开始。但是会要先对比一下两方文件,要耗时一段时间
# -j : jobs 并发数 本地一般设置在 8~32,服务器上在 96~192
# -p : 分块的每块并发数 本地一般设置在 8~32,服务器上在 96~192
# example
tosutil cp -r -u -j 96 -p 96 /Users/jiaqiwu/Desktop/Project tos://mm-jiaqi-test/Code
# 则会把本地 Project 文件夹传输到桶 mm-jiaqi-test 的 Code 文件夹下。形成Code/Project/
# python 上传和下载文件夹
from easy_tos import *
upload_dir_via_tosutil(local_dir, tos_dir, config, flat=True, jobs=96, chunk_jobs=96, verbose=True)
download_dir_via_tosutil(tos_dir, local_dir, config, flat=True, jobs=96, chunk_jobs=96, verbose=True
# 注:若 flat = True, 则不包含 tos 父文件夹本身。
# 传输文件(把 -r 去掉)
tosutil cp -u -j 96 -p 96 {tos_path} {local_dir}/ #结果:{local_dir}/tos_file
tosutil cp -u -j 96 -p 96 {local_path} {tos_dir}/ #结果:{tos_dir}/local_file
tosutil cp -u -j 96 -p 96 {tos_path} {tos_dir}/   #结果:{local_dir}/tos_file
# 注意!!!目标路径一定是以/结尾的文件夹路径。不然就会把该文件传输到 target_dir的父目录下,名字为target_dir
# python 上传和下载文件
from easy_tos import *
upload_file_via_tosutil(local_path, tos_path, config, flat=True, jobs=96, chunk_jobs=96, verbose=True)
download_file_via_tosutil(tos_path, local_path, config, flat=True, jobs=96, chunk_jobs=96, verbose=True)



场景二:得到 tos 某个文件夹下的所有文件路径或者子文件夹路径

from easy_tos import *
# 得到桶 mm-data-general-model-v1 下面 rendering/nvdiffrast_render_v1_diffuse/ 的所有子文件夹。并把结果存到指定的 txt 路径。
tos_dir = "tos://mm-data-general-model-v1/rendering/nvdiffrast_render_v1_diffuse/"
res = list_all_subdirs_under_prefix(tos_dir, config, save2txt=True, custom_save_path="v1_diffuse_rendering.txt")

# 得到桶 mm-data-general-model-v1 下面 glb_models/ 所有的文件路径。 并把结果存到指定的 txt 路径。
tos_dir = "tos://mm-data-general-model-v1/glb_models/"
res = list_all_files_under_tos_dir(tos_dir, config, save2txt=True, custom_save_path="v1_glbs.txt")



场景三:tos上某个文件路径是否存在

from easy_tos import *
tos_path = "tos://mm-data-general-model-v1/glb_models/000-steel-stairs-fire-escapes-100465bd4888438aae77e058ef071940.glb"
print(check_tos_file_exists(tos_filepath=tos_path, config=config))
# return True if exists
# return False if not 



场景四:下载tos文件夹子集

# 有时候我们不想下载整个文件夹,只想要这个文件夹下的一部分文件或文件夹,我们有我们要的文件的信息,通常是 uid

from easy_tos import *
# 多线程下载 tos 目标文件夹下的 部分子文件
uids = [uid.strip() for uid in open("/home/jiaqi/Data_Engine/v1_all_uid.txt").readlines()]
tos_parent_dir = "tos://mm-data-general-model-v1/glb_models/"
file_type = "glb"
local_dir = "/home/jiaqi/Data_Engine/v1_glb"
download_files_under_tos_dir(tos_parent_dir, uids, file_type, local_dir, config, jobs=96, chunk_jobs=96, verbose=True)


# 多线程下载 tos 目标文件夹下的 部分子文件夹
uids = [uid.strip() for uid in open("/home/jiaqi/Data_Engine/v1_all_uid.txt").readlines()]
tos_parent_dir = "tos://mm-data-general-model-v1/rendering/"
local_dir = "/home/jiaqi/Data_Engine/v1_glb"
download_dirs_under_tos_dir(tos_parent_dir, uids, local_dir, config, jobs=96, chunk_jobs=96, verbose=True)



场景五:流式下载和上传

支持读取

  • pt
  • glb
  • jpg, png
  • json
  • txt
  • npz

支持保存

  • torch tensor
  • python dict
  • str
  • PILLLOW Image
  • numpy array
from easy_tos import *
## 流式下载
torch_tensor = read_tos_tensor(tos_path, config) 
tm = read_tos_glb_via_trimesh(tos_path, config)
gltf_mesh = read_tos_glb_via_gltf(tos_path, config)
pillow_img = read_tos_img(tos_path, config)
json_dict = read_tos_json(tos_path, config)
txt_str = read_tos_txt(tos_path, config)
np_array = read_tos_npz(tos_path, config)


## 流式上传
# 保存 tensor 至 tos
import torch 
feature = torch.rand(100, 100)
tos_save_path = "tos://mm-jiaqi-test/test.pt"
save_tensor2tos(feature, tos_save_path, config)

# 保存 numpy array 至 tos
import numpy as np
np_arr = np.random.rand(4, 5)
tos_save_path = "tos://mm-jiaqi-test/test.npy"
save_array2tos(np_arr, tos_save_path, config)


# 保存 dict 至 tos,以 json 格式存储
toy_dict = {"test": 1}
tos_save_path = "tos://mm-jiaqi-test/test.csv"
save_dict_to_tos_json(toy_dict, tos_save_path, config)

# 保存 str 至 tos, 以 txt 格式存储
toy_str = "test"
tos_save_path = "tos://mm-jiaqi-test/test.txt"
save_string(toy_str, tos_save_path, config)

# 保存 PILLOW Image class to TOS
from PIL import Image
pil_img = Image.open("test.png")
tos_save_path = "tos://mm-jiaqi-test/test.png"
save_pil_img2tos(pil_img, tos_save_path, config)
