False positive on "unresolved import" for `tensorflow.keras`

[kbrose]

Environment data

• VS Code version: 1.38.0
• Extension version (available under the Extensions sidebar): 1.38.0
• OS and version: macOS Mojave, 10.14.6
• Python version (& distribution if applicable, e.g. Anaconda): 3.6.8
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): pyenv
• Relevant/affected Python packages and their versions: tensorflow 1.14, 2.0
• Jedi or Language Server? (i.e. what is "python.jediEnabled" set to; more info How to update the language server to the latest stable version #3977): language server (setting is false)

Expected behaviour

Create python file

from tensorflow.keras.layers import Input

inp = Input(shape=(1,))
print('Done!')

Expect no errors, expect a useful information tooltip when hovering over Input.

Running this python file prints "Done!", i.e. this is not actually an unresolved import.

Actual behaviour

unresolved import error is shown. No useful information tooltip.

Other note

If I change the import to

from tensorflow.python.keras.layers import Input  # inserted ".python"

things work as expected. This is a non-standard, undocumented import path (so I'd rather not do it).

Steps to reproduce:

1. Create a python file containing above code.
2. Observe error.

Related issues

This seems related to #6241, but as best as I can tell there's no sys.path shenanigans going on inside tensorflow (and thus not a duplicate). The two following files look reaosnable to me, but I'll admit I don't know much about how the tensorflow pypi package is created. There could be weird stuff inserted at build time.
