为 pytorch 安装预训练模型时出错

Question

我正在使用 Windows 10 机器（是的，我知道，别笑！）和 python 3.7，我正在尝试在此处安装预训练模型：

https://github.com/meliketoy/fine-tuning.pytorch

网站建议的命令是：

$ git clone https://github.com/Cadene/pretrained-models.pytorch.git
$ pretrained-models.pytorch
$ python setup.py install

虽然网站上说这是针对 Python 3.5，而我有 3.7，但我认为 3.7 版本应该是向后兼容的，对吧？

我成功运行了git clone，而pretrained-models.pytorch 实际上是一个cd 命令（这让我愣了一秒钟！）。然后我遇到了python setup.py install的麻烦

我得到的错误是：

[Errno 2] No such file or directory: 'build\\bdist.win-amd64\\egg\\pretrainedmodels\\models\\resnext_features\\__pycache__\\resnext101_32x4d_features.cpython-37.pyc.1702181039952'

我该如何解决这个错误？

编辑（回应评论）：有人要求提供完整的回溯。在这里！

一种选择是使用 docker 映像，我经常使用的是来自 jupyter 的 datascience-notebook 映像。

为此：

• 1. 为 Windows 安装 docker 桌面，参考这个link。
• 1. 在 Docker Destop 设置中启用文件共享

从C:users\amtre 可以看出，我可以将任何子目录挂载到容器中，例如，Documents 文件夹中的所有子目录。

• 1. 一旦 docker 可以访问容器的挂载目录，我们将使用 jupyter datascience-notebook，因为它已经默认附带了一些软件包。在终端上输入

docker run -it -e GRANT_SUDO=yes --user root --rm -p 8888:8888 -p 4040:4040 -v C:/users/amtre/Documents:/home/jovyan/work jupyter/datascience-notebook

拉取 docker 镜像需要一些时间，但最后您将获得访问笔记本的 URL，如上图所示。

4. 在 Jupyter 中，打开终端并输入

git clone https://github.com/Cadene/pretrained-models.pytorch.git
cd pretrained-models.pytorch
python setup.py install

这也会安装'torch', 'torchvision', 'munch', 'tqdm'，因为它在setup.py 上的install_requires。安装完成后，您应该可以开始使用预训练模型了
