【WSL安装测试paddle报错】 The third-party dynamic library (libcuda.sois not configured correctly.

安装paddle后使用python测试paddle是否可用

import paddle
paddle.utils.run_check()

报出如下错误

Running verify PaddlePaddle program …

W0805 12:10:55.927047 5446 dynamic_loader.cc:305] The third-party dynamic library (libcuda.so) that Paddle depends on is not configured correctly. (error code is libcuda.so: cannot open shared object file: No such file or directory)
Suggestions:

1. Check if the third-party dynamic library (e.g. CUDA, CUDNN) is installed correctly and its version is matched with paddlepaddle you installed.
2. Configure third-party dynamic library environment variables as follows:

• Linux: set LD_LIBRARY_PATH by export LD_LIBRARY_PATH=...
• Windows: set PATH by `set PATH=XXX;
  Segmentation fault

这是paddle没有找到libcuda.so，在wsl中，该文件在/usr/lib/wsl/lib路径下。
在.bashrc下加入该路径即可。

export LD_LIBRARY_PATH=/usr/lib/wsl/lib:$LD_LIBRARY_PATH

成功。
