为什么我在运行 pytorch 代码时遇到“UserWarning：NumPy 模块已重新加载（第二次导入）...”？

Question

我的环境： Anaconda、Python 3.8.8、Pytorch1.8.1+cu111
\n问题：当我运行下面的代码时，出现以下错误：

\n

UserWarning: "D:\\Anaconda3\\envs\\pytorch\\lib\\site-packages\\torch\\cuda\\amp\\autocast_mode.py:5: UserWarning: The NumPy module was reloaded (imported a second time). This can in some cases result in small but subtle issues and is discouraged."\n

\n

代码：

\n

from PIL import Image\nfrom torchvision import transforms\n\nimg_path = "data/train/ants_image/0013035.jpg"\nimg = Image.open(img_path)\n\ntensor_trains = transforms.ToTensor()\ntensor_img = tensor_trains(img)\n\nprint(tensor_img)\n

\n

但代码有效。为什么会出现上面的错误信息\xef\xbc\x9f
