返回的True，說明可以
通過pycharm卻不行，如下圖，返回False
解決辦法：
1.修改~/.bashrc
將pycahrm的路徑加到環境中，示例如下：
|
1
|
alias pycharm="bash /home/answer/文檔/pycharm-professional-2019.3.2/pycharm-2019.3.2/bin/pycharm.sh" |
刷新生效：
|
1
|
source ~/.bashrc |
2.修改pycharm中的環境變量
選擇pycharm 菜單欄Run ——> Run-Edit Configurations ——> Environment variables——> 將cuda的路徑加進去 例如：LD_LIBRARY_PATH=/usr/local/cuda-10.1/lib64
在運行就可以了
