完整命令输出的日志。

不太确定错误是什么。如果我使用第二个命令安装它只是说 pytorch 不满足要求。我安装了 pytorch 但仍然是同样的问题

Answer 1

您的基础环境中的 Python 版本已过时。这不一定是个问题(但您仍然可能要考虑安装 anaconda3/miniconda3 版本)，因为您可以使用更新的 python 版本创建一个新环境:

创建新环境并激活它:

conda create -n easyocr python=3.8
conda activate easyocr

安装 PyTorch(根据您的 CUDA 版本从 here 获取正确的命令):

conda install pytorch torchvision torchaudio cudatoolkit=10.2 -c pytorch

然后你应该能够运行:

pip install easyocr
