$ pip install cudatoolkit==10.1
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement cudatoolkit==10.1 (from versions: none)ERROR: No matching distribution found for cudatoolkit==10.1

失败了，但是conda却可以安装：

$ conda install cudatoolkit=10.1
