ModuleNotFoundError: No module named 'tensorflow', even when tensorflow is installed

Question

I am trying to install tensorflow for one of my machine learning projects. However, even though I have installed it, I still get this error

ModuleNotFoundError: No module named 'tensorflow'

To help illustrate this better, I have created a test.py file, with the following content:

import tensorflow as tf

print('Hello world!')

However, still the same error, on line 1.

Relevant questions:

I've tried doing many other answers, but none of them seems to help. Any answers would be appreciated.

Here's some debugging outputs that might help:

Answer 1

I fixed it! Special thanks to the folks at the Tensorflow Talk slack who helped me, especially @akofman.

It was a combination of 2 problems:

Problem 1

It seems that one of the reasons it was failing was due to one of tensorflow's dependencies being outdated/misinstalled/something. The dependency is h5py. I found out about this by attempting to run import tensorflow in the python interpreter (type python), which gave me a long stack trace, unlike the test file (see problem 2). I fixed this by reinstalling the dependency.

Problem 2

It turns out that I have 3, that's right, 3!, versions of python on my computer

python -V ---> 3.6.0

python -V (in an anaconda enviorment) ---> 3.6.7

py -V ---> 3.7.0

I was running my test file with py, which is apparently 3.7.0 (I thought it was synonymous with python), I guess tensorflow doesn't support that version?
