我正在尝试安装 tensorflow 1.15，它安装得很好。当我再次运行pip install tensorflow==1.15 时，它会显示以下屏幕：

这意味着安装了tensorflow，对吗？我使用的python是V3.7.7

我使用 Pycharm 运行以下代码作为测试：

import tensorflow as tf
print(tf.__version__)

它给我一个错误如下：

Traceback (most recent call last):
  File "C:/Python394/for_trials.py", line 1, in <module>
    import tensorflow as tf
ModuleNotFoundError: No module named 'tensorflow'

好像是无法识别tensorflow，或者python与Tf1不兼容。但是，按照指南，python 3.7 及更早版本与 Tf1 兼容。

您能帮我解决安装 Tf1 的问题吗？

谢谢

【参考方案1】：

问题是你的机器上已经很好地安装了tensorflow，但是在哪个环境下呢？为了让 pycharm 看到 tensorflow，tensorflow 必须安装在 pycharm 用来执行代码的相同环境中。但是，例如，如果您的 pycharm 配置为在虚拟环境中执行代码，并且 tensorflow 安装在 anaconda 中，则它无法正常工作。所以可以做的简单的解决办法就是把pycham的环境改成安装tensorflow的环境

【讨论】：

是的，我注意到安装的Anacoona是python V3.8，但是我在哪里可以得到python 3.7的anaconda。我无法上网。当我单击此处下载时，anaconda.com/products/individual 我只得到适用于 python 3.8 的 Anaconda

为什么要在 python 3.7 中使用 anaconda？ 3.8版不错。您安装 3.8 版并在 pycharm 中更改解释器版本，如下所示：为什么要将 anaconda 用于 python 3.7？ 3.8版不错。您安装 3.8 版并在 pycharm 中更改解释器的版本，如下所示：（我无法在答案中添加屏幕截图，因此我将其放在另一个答案中）

是的，但是当我从 anaconda 安装 tensorflow 1.15 时，它会拒绝。它给出了一个错误，即 tensorflow 的版本必须是 2.2 及更高版本。为此，我正在寻找适用于 python 3.7 的 anaconda

dans ce cas tu retrograde simplement la version de python comme : conda install python 3.7

oui, c March bien mtn ... j'ai installe le anaconda pr python 3.7, et mtn tt va b1
