I have a python package declared within the extension, and I can import it directly when accessing from the extension code. How can I import that extension in the Slicer python console?

I’ve done this before, I know it is possible, but I cannot find it in the hierarchies of `slicer.modules.*` etc.

Do you mean something like this?

```auto
self.showStatusMessage(' Importing lungmask AI ...')
try:
    import lungmask
except ModuleNotFoundError:
    self.showStatusMessage(' Installing lungmask AI ...')
    lungmaskPackage = "https://github.com/JoHof/lungmask/archive/master.zip"
    slicer.util.pip_install(lungmaskPackage)
    import lungmask

```

With the help of @DeepaKrishnaswamy I figured this out.

To be more specific, I wanted to import this package:

> <https://github.com/QIICR/TCIABrowser/blob/master/TCIABrowser/TCIABrowserLib/TCIAClient.py>

Which is part of this extension:

> **[GitHub - QIICR/TCIABrowser: 3D Slicer module for browsing and downloading...](https://github.com/QIICR/TCIABrowser)**
>
> 3D Slicer module for browsing and downloading medical imaging collections from The Cancer Imaging Archive (TCIA). - GitHub - QIICR/TCIABrowser: 3D Slicer module for browsing and downloading medical...

Which is very simple once you know how to do it. I hope I will remember it for the next time!

```python
from TCIABrowser import TCIAClient

```
