with python 3.6, Could not find a version that satisfies the requirement tensorflow (from versions: ) No matching distribution found for tensorflow
if you have anaconda do conda install tensorflow. anaconda version of tensorflow is faster than pip anyways.
C:\WINDOWS\system32>pip install tensorflow

Collecting tensorflow

  Could not find a version that satisfies the requirement tensorflow (from versions: )
No matching distribution found for tensorflow

I installed the Python (3.6 64-bit), and wanna install tensorflow in Anaconda3.
And I upgraded pip to the latest version, 19.0.1.
Requirement already up-to-date: pip in c:\anaconda3\lib\site-packages (19.0.1)
So, how can I solve this problem?
