为什么在pycharm里成功下载TensorFlow模块，却在import时报错

Question

报错信息如下：

Traceback (most recent call last):
  File "D:\PycharmProjects\study\venv\lib\site-packages\tensorflow\python\pywrap_tensorflow.py", line 64, in <module>
    from tensorflow.python._pywrap_tensorflow_internal import *
ImportError: DLL load failed: 找不到指定的模块。

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "D:/PycharmProjects/study/TensorFlow/tensorflow入门.py", line 2, in <module>
    from tensorflow import keras
  File "D:\PycharmProjects\study\venv\lib\site-packages\tensorflow\__init__.py", line 41, in <module>

Answer 1

这是DLL load failed，就是DLL加载失败。分析原因可能是安装TF的时候没有安装完全。建议可以使用conda方法来组织Python环境。

具体步骤可以仿照我的手把手博客内容：《『带你学AI』开发环境配置之Windows10篇：一步步带你在Windows平台开发深度学习（Windows上TensorFlow1与TensorFlow2的CPU与GPU安装与开发使用指南）》https://xiaosongshine.blog.csdn.net/article/details/112249592
