Thanks for the issue.

According to the log, this is the current interpreter you have set:

/Users/anupamghosh/workspace/venv/servers/bin/python

Is that where the package is installed? How did you pick your interpreter? The UI you're showing in the screenshot isn't the normal UI for picking one.

Here's the log output for Pylance failing to find the pytz package:

How is virtualenv servers getting set? I have set the virtualenv to fst2. The screenshot in the bottom right shows,
that for the current file the virtualenv is fst2.

To set the virtualenv I used this flow ⌘ + shift + p -> > Python: select interpreter -> Selected the workspace folder fst2 -> gave the fst2 virtualenv path ~/workspace/venv/fst2/bin/python

Following is my workspace configuration

{
    "folders": [
        {   
            "path": "servers"
        },  
        {   
            "path": "firespotter/prober"
        },  
        {   
            "path": "plivo"
        },  
        {   
            "path": "firespotter/fst2"
        },  
        {   
            "path": "kamailio"
        },  
        {   
            "path": "interactiveconsole"
        }   
    ],  
    "settings": {
        "python.analysis.extraPaths": ["/Users/anupamghosh/workspace/dialpad/firespotter/fst2"],
    }   
}

Below image shows my directory structure of the workspace

It seems you're working in a multi-root workspace scenario. If you open the file where this package is being used and select the environment where the package is installed from the bottom-right corner of VS Code, does the error go away?

pylance.could.not.resolve.mov

It still didn't work
