Pytorch | 报错 The given NumPy array is not writeable,and PyTorch does not support non-writeable tensor

1. 报错
2. 解决方案
- 2.1 查找 mnist.py 文件
- 2.2 修改 mnist.py 文件
- 2.3 问题解决

1. 报错

/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)

2. 解决方案

2.1 查找 mnist.py 文件

\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/。

2.2 修改 mnist.py 文件

\qquad修改mnist.py文件的第 498498498 行，删除copy=False。

2.3 问题解决
