python - 安装Tensorflow时出现环境错误

Question

安装 Tensorflow 时，它说我丢失了一个文件，但我不知道如何修复它或获取该文件

我已尝试重新下载 python，但仍然缺少该文件

pip install Tensorflow

我想要的是完成安装。 这是错误消息:

C:\Users\MYUSER\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.7_qbz5n2kfra8p0\LocalCache\local-packages\Python37\site-packages\tensorflow_estimator\python\estimator\canned\linear_optimizer\python\utils\__pycache__\sharded_mutable_dense_hashtable.cpython-37.pyc'

Answer 1

这是一个典型的 Windows 长文件路径问题。禁用 MAX_PATH 限制；相关说明可以例如被发现here :

3.1.2. Removing the MAX_PATH Limitation

Windows historically has limited path lengths to 260 characters. This meant that paths longer than this would not resolve and errors would result.

In the latest versions of Windows, this limitation can be expanded to approximately 32,000 characters. Your administrator will need to activate the “Enable Win32 long paths” group policy, or set the registry value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem@LongPathsEnabled to 1.

之后，重新启动并重试安装。
