/home/dong/anaconda3/lib/python3.8/site-packages/torchvision/datasets/mnist.py:498: 
UserWarning: The given NumPy array is not writeable, and PyTorch does not support non-writeable tensors. 
This means you can write to the underlying (supposedly non-writeable) NumPy array using the tensor. 
You may want to copy the array to protect its data or make it writeable before converting it to a tensor. 
This type of warning will be suppressed for the rest of this program. 
(Triggered internally at  /pytorch/torch/csrc/utils/tensor_numpy.cpp:180.)
  return torch.from_numpy(parsed.astype(m[2], copy=False)).view(*s)

qquad 根据报错：

/home/dong/anaconda3/lib/python3.8/site-packages/torchvision/datasets/mnist.py:498: 

可以知道mnist.py文件所在位置为/home/dong/anaconda3/lib/python3.8/site-packages/torchvision/datasets/。

qquad 修改mnist.py文件的第 498 498 498 行，删除copy=False。
