Hi message board,

Is there a command to let me install a specific version of SimpleITK with pip.

I would like to install v 1.2.4 because I’m looking for the old registration framework that used discreteGaussianImageFilter rather than RecursiveGaussianImageFilter for its smoothing.

Something like:  
python -m pip install SimpleITK -v 1.2.4

Hello @Nick_Rubert ,

That’s a general `pip` question, so as expected the answer is in [the pip documentation](https://packaging.python.org/tutorials/installing-packages/#installing-from-pypi). Recommend reading it as it describes how to specify a range of versions, a specific package version, or the latest version that is compatible with a specific version.

For what you want the syntax is:

```auto
python -m pip install SimpleITK==1.2.4

```
