mge-lpips 0.1.0

LPIPS Similarity Metric for MegEngine

LPIPS for MegEngine

MegEngine port for LPIPS metric.

Get Started

Run pip3 install mge-lpips to install this package. The provided mge_lpips.LPIPS is a normal MegEngine M.Module which can be used as a metric or a loss function.

import numpy as np
import megengine as mge
from mge_lpips import LPIPS

metric_lpips = LPIPS(net="alex")

in1 = np.random.uniform(-1, 1, size=(2, 3, 256, 256)).astype(np.float32)
in2 = np.random.uniform(-1, 1, size=(2, 3, 256, 256)).astype(np.float32)

d = metric_lpips(mge.Tensor(in1), mge.Tensor(in2))
