Tensorflow 不会使用 Anaconda 导入

Question

I am trying to get Gpt-2 to work on Win10 intel i7 950 and have set up an env in Anaconda (Python 3.5, Tensorflow 1.12) but I am not even getting past the import of tensor flow. I have read several questions regarding similar problems but none of the fixes/workarounds have worked for me.

import tensorflow as tf

Traceback (most recent call last):
  File "D:\anaconda3\envs\gpt-2\lib\site-packages\tensorflow\python\pywrap_tensorflow.py", line 58, in <module>
    from tensorflow.python.pywrap_tensorflow_internal import *

    return _load(spec)

During handling of the above exception, another exception occurred:

I have tried up/down-grading packages but from my understanding, Gpt-2 will not work with higher versions of Python and TensorFlow.

*edit I tried the "conda create --name tf_gpu tensorflow-gpu" which installs a full tensorflow environment, I also tried downgrading to tensorflow 1.5, both work but none of them works with gpt-2

*edit 2 I looked at the code that generates the error message and it is not a dll that is being loaded despite what the message says. It is a.pyd file: "\lib\site-packages\tensorflow\python\_pywrap_tensorflow_internal.pyd"

Even if you do a pip install, sometimes this DLL error may appear while trying to import tensorflow. Go to https://www.tensorflow.org/install/pip then click on Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 as given in screenshot.

Now download and install the required executable 64 bit or 32 bit. This resolved my issue. Please try this.
