问题背景
运行yolov5时出现下面的warning,虽然不影响运行,但是看着很难受。在python环境下import torchvision
也是下面的问题,说明就是无法加载torchvision库。
/home/firefly/anaconda3/envs/yolo/lib/python3.8/site-packages/torchvision/io/image.py:13:
UserWarning: Failed to load image Python extension: warn(f"Failed to load
image Python extension: {e}")
问题原因
pytorch和torchvision的版本没对应上,下图是pytorch和torchvision的正确对应版本,请根据自己情况,重装pytorch或者重装torchvision。
问题解决
1、进入我们的anaconda环境,pip list
显示我们的所有库。可以看到我这里的torch是1.11.0,根据上表得知对应的torchvision应该是0.10.0,而我安装的是0.12.0,所以报错。
2、pip3 uninstall torchvision卸载torchvision。
3、pip3 install torchvision==0.10.0指定安装torchvision的版本。
我们再次import torchvision,没有任何报错,成功导入,问题解决!
