ImportError: Could not find ‘cudart64_100.dll‘.

ImportError: Could not find ‘cudart64_100.dll’.

TensorFlow requires that this DLL be installed in a directory that is named in your %PATH% environment variable.

出现上面的错误的话，参考：

1. https://github.com/tensorflow/tensorflow/issues/31701
2. https://blog.youkuaiyun.com/aya_tao/article/details/100056269?utm_medium=distribute.pc_relevant.none-task-blog-title-11&spm=1001.2101.3001.4242

如果上述都不能解决，出现了奇怪现象。例如：

在CMD中可以正确import tensorflow
在PyCharm中出现上述错误

并且：

1. 有cuadrt64_100.dll
2. 将C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\bin加入了环境变量

依旧报错，那请重启你的电脑。
