如何解决PyCharm中的TensorFlow错误？

Question

tensorflow_安装_测试。派克

import tensorflow as tf
import os
os.environ["CUDA_VISIBLE_DEVICES"] = "-1"

print(tf.__version__)

以下是输出：

我该如何解决这个问题？

Answer 1

根据StackOverflow上的链接，这不仅仅是你的问题。导致错误的真正线索是WinError126。我可以在ErrorTools上在线找到一些原因。如果您使用的是Anaconda环境，我的建议是创建一个新环境并在那里安装TensorFlow，看看它是否有效。如果没有，可能是您的DLL有问题。

在这种情况下，另一种选择是按照堆栈跟踪进行调试，直到达到以下行：self_handle=\u dlopen（self.\u name，mode）在\u初始化\u中。py位于ctypes目录下。此时，您可以检查self的值是多少_命名，并查看它是否与上面链接的StackOverflow问题中列出的任何问题相匹配。

如果您不确定在何处查找所有这些文件以供将来自己调试，我建议您使用VoidTools，因为它执行的搜索比文件资源管理器快得多。
