我已經安裝了 Tensorflow 但我無法在 Python 中導入它：ImportError: cannot import name 'descriptor' from 'google.protobuf'（未知位置）

Question

我已經在我的 Windows 10 筆記本中成功安裝了 Tensorflow：

但是，當我嘗試在 Python 中導入它時，我收到一條錯誤消息：

C:\WINDOWS\system32>conda activate base

(base) C:\WINDOWS\system32>python

>>> import tensorflow
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'tensorflow'

當我運行conda list我得到：

更新

我遵循了 Rachayita 的建議，但我已經安裝了 Tensorflow 1.4，我想要 tensorflow-gpu 2.0

從我的基本 Anaconda 環境中，我卸載了已安裝的 tensorflow-gpu 2.0，然后按照官方 tensorflow 文檔使用 pip 重新安裝它。

Answer 1

您應該通過在 Anaconda 提示符下運行以下命令，將其與 Anaconda 一起安裝：

> conda create -n tf-gpu tensorflow-gpu
> conda activate tf-gpu

這是完整的文檔 -https://docs.anaconda.com/anaconda/user-guide/tasks/tensorflow/

Answer 2

您必須使用 pip 安裝 tensorflow 安裝 tensorflow 而不是 tensorflow-gpu

Answer 3

您是否在“conda activate base”之后運行了“pip install tensorflow-gpu”？

如果不是，那么這就是您需要做的，因為 tensorflow 不會安裝在您的虛擬環境“基礎”中。
