Hi everyone,

I’m trying to pip install packages from the Python console in Slicer using the following commands:

```auto
import pip
pip.main(['install','pandas'])

```

This works perfectly well on macOS, but on Windows I get the following error (on both 10 and 11, on different machines and with different versions of Slicer: 4.11, 4.13 and 5.2.1):

```auto
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

```

Does anyone else have the same problem?

Thanks in advance!

`pip.main()` is indeed old and deprecated within `pip`.

To install python packages using the python console in Slicer you should use `pip_install`. See the following resources below for examples and more details.
