ERROR During Install MONAI Label #1801

[VuDuc5]

Hello, I am trying to install the MONAI Label and trying to download radiology app using the code " !monailabel apps --download --name radiology --output apps". I got this Problem:
"(Monai) C:\Users\user>monailabel apps --download --name radiology --output apps

Also, the AttributeError: 'PathDistribution' object has no attribute 'name'" happens when I try to start the MONAI server:

This was fixed in 30e97b4, please update your MONAILabel.

Hi, I was still getting the same error with the latest version of monailabel (v0.8.5)

I was able to fix it by modifying the monailabel config.py file in my environment.

Update the below function to look like this.

def is_package_installed(name):
    try:
        from importlib.metadata import distributions
        return name in [dist.metadata['Name'] for dist in distributions()]
    except:
        # Fallback method
        try:
            import pkg_resources
            pkg_resources.get_distribution(name)
            return True
        except:
            return False

Hope this helps.
