Autocompletion doesn't work for some numpy's functions

[duskmoon314]

I have searched issues and found microsoft/vscode-python#679. But it seems out of date since it was updated on 11 Jul 2018.

Environment data

• VS Code version: 1.38.1
• Extension version (available under the Extensions sidebar): 2019.9.34911
• OS and version: Windows_NT x64 10.0.18362
• Python version (& distribution if applicable, e.g. Anaconda): 3.7.2 (64-bit)
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): venv
• Relevant/affected Python packages and their versions:
  • pyright 1.0.68
  • Visual Studio IntelliCode 1.1.9
• 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 vscode-python#3977): "python.jediEnabled": false

Expected behaviour

I expect to see what parameters I need to fill and what will those functions return to me.

Actual behaviour

After I imported numpy in the way import numpy as np, I tried to use some math functions. When I tried to type in np.sin, nothing about sin appeared. I could only see other methods like _sanity_check. This happened to cos and exp. But for matmul, sum, dot, autocompletion and hints sometimes work well. (It seems that after vs intellicode run for a moment, they work well for matmul. At the buttom of how to use is matmul: unknown)

Besides, when I moved the cursor onto np.sin(), it showed sin: unknown

p.s. On another computer which I don't install visual studio intellicode, autocompletion works. But it only tells me sin and matmul are ufunc, which is no use.

Steps to reproduce:

1. import numpy as np
2. try to type in np.sin

XXX

Don't know what I need to paste here. There a lot of logs in Console under the Developer Tools

I have tried to uninstall python extension and reinstrall, nothing happen.

I find a solution, using Jedi. But I want to try coding with visual studio intellicode, which needs me to use MS language server

Very likely #1414. Does reloading cause the members to show up?

Maybe I have seen the order is inconsistent. But I haven't seen np.sin show up.

I will keep my eyes on it.
