tensorflow 无法导入

Question

我最近创建了一个新的 anaconda 环境来安装最新版本的 Tensorflow。之后，我使用了以下命令conda install tensorflow. 我使用以下命令重新安装了 tensorflow：pip install --upgrade --no-deps --force-reinstall tensorflow 我在这个环境中使用的 python 版本是： Python3.7.9。 当我想导入 tensorflow 时，它会抛出这个错误：

谁能告诉我这是怎么回事？

Answer 1

尽量不要混合使用 conda 和 pip 安装。

如果您不想删除环境并重新开始，则：

• 尝试运行 conda remove tensorflow 以从 conda 中删除 tensorflow（如果您想坚持使用 pip）
• 尝试运行pip uninstall tensorflow，然后运行conda install protobuf（如果您想坚持使用conda）

但最明智的做法可能是从新的 conda/virtualenv 环境开始，然后运行 ​​conda install tensorflow protobuf 或 pip install tensorflow protobuf。
