如何在intel Mac 不用gpu只用cpu？

[Stone-0211]

如题，我无法使用cuda，每次都报错，想看看能不能换成cpu，时间长点没关系 或者大佬能不能帮我看看为啥cuda会报错： /Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/torchvision/models/_utils.py:208: UserWarning: The parameter 'pretrained' is deprecated since 0.13 and may be removed in the future, please use 'weights' instead. warnings.warn( /Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/torchvision/models/_utils.py:223: UserWarning: Arguments other than a weight enum or None for 'weights' are deprecated since 0.13 and may be removed in the future. The current behavior is equivalent to passing weights=ResNet18_Weights.IMAGENET1K_V1.

搜索一下代码里面,主要是train.py和test.py，把cuda改成cpu就好

改完了，但他又报这个错了😂：FileNotFoundError: [Errno 2] No such file or directory: 'checkpoint_path' 请问要把checkpoint-iter199999.pth放哪里啊？ 谢谢！

随便放个地方，然后把路径记下来，替换掉checkpoint_path就好啦

又报了这个错😓： RuntimeError: Attempting to deserialize object on a CUDA device but torch.cuda.is_available() is False. If you are running on a CPU-only machine, please use torch.load with map_location=torch.device('cpu') to map your storages to the CPU.

把test.py中的第41行改成model_weight = torch.load(opt.pretrained_model, map_location='cpu')

[Stone-0211]

这又是啥原因？TypeError: cannot pickle 'Environment' object

参见issue#23，把test.py里的DataLoader的num_workers改成0

好像cuda又出问题了：AssertionError: Torch not compiled with CUDA enabled

等我抽空整理一个cpu版本
