Pyright cannot resolve the wandb module import, although it can resolve every other import.

[oyarsa]

Describe the bug
Pyright cannot resolve the wandb module import, although it can resolve every other import.

To Reproduce
I am using poetry, but running pyright directly from the command line (inside the venv) results in the same problem.

• Start a new venv
• Import the module wandb in a file, alongside any other installed dependency, say, sklearn
• Run pyright (or pylance from VSCode)
• Pyright appropriately resolves the sklearn import, but not wandb
• Pyright gives the error error: Import "wandb" could not be resolved (reportMissingImports)

Expected behavior
Pyright can resolve the wandb import correctly

VS Code extension or command-line
This happens with Pylance 2020.6.1 and pyright 1.1.48

Additional context
What strikes me as odd is that pyright can find the module (Resolved import with file [...]), but for some reason, it still doesn't resolve it.

Thanks for the bug report.

I'm not able to repro the problem as described. Perhaps there are additional details. What form of an import statement are you using in your code? Are you using import wandb or from wandb import x?

Here's what I see when I try to repro:

[oyarsa]

Thank you for replying this fast. Here's... something:

The file a.py only contains the import. When I run pyright on the same directory, no problem. When I run at the root of the project, there's the problem. In fact, I just found out (not on the screenshot), that any other directory but the project root works.

A few minutes of testing later...

Okay, I think I figured this out: creating a folder with the same name as the module in the working directory creates this error. The initial scenario had a wandb folder at the project root. I tested with a clean project, and the same happens: pyright gives this error if there's a folder with the same name as module in the directory where I call the program.

test.py is just

import wandb
print(wandb.__version__)

Thanks for the additional clues. This is a bug in Pyright's import resolution code. It should always favor a third-party library import if a local import can't be found. A fix will be included in the next version of Pyright.

This is addressed in Pyright 1.1.49, which I just published.
