easyocr WARNING CUDA not available - defaulting to CPU. Note: This module is much faster with a GPU

Question

I reference this post to check my cuda driver. It's meet the requirements. But torch still can't use GPU.

operating system info： Windows 10

package and env info：

Any help will appreciate.

Answer 1

Currently, PyTorch on Windows only supports Python 3.7-3.9; Python 2.x is not supported.

Ref

Change python version to 3.8 can work.

Answer 2

I had the same issue. After searching for a while, I found on the JaidedAI/EasyOCR github repository the following note:

For Windows, please install torch and torchvision first by following the official instructions here https://pytorch.org. On the pytorch website, be sure to select the right CUDA version you have. If you intend to run on CPU mode only, select CUDA = None.

After uninstalling torch and easyOCR, I reinstalled torch first, and then reinstalled easyOCR. It seems to have fixed the issue.

Hope this helps.
