I am attempting to use ALPACA. When using this tool for the first time I am prompted that open3D will be installed. I allow it do do this but then I get a series of errors which are beyond my ability to troubleshoot. Any suggestions would be very welcome.

@bcolbert  
For a brief period we used git to install open3d, which unfortunately wasn’t as commonly available. Looks like you installed the SlicerMorph during that time. Please update your SlicerMorph installation following [this instructions](https://github.com/SlicerMorph/SlicerMorph#updating-slicermorph).

Open the python window, and type or copy/paste these commands

```auto
pip_install('notebook==6.0.3')
pip_install('open3d==0.10.0')
pip_install('pycpd')

```

and then try using alpaca

Sorry to revice an old post but I am having a similar error. When I run the command lines you suggested I now get an error on: pip\_install(‘open3d==0.10.0’):

```auto

```

Is there a solution to this?

It appears you have switched from using Slicer 4.11.20210226 to now using Slicer 4.13.0-2022-02-20. This corresponds with a switch from Python 3.6 to Python 3.9. `open3d` does not have Python 3.9 whl files to install with version 0.10.0 as that version was released prior to Python 3.9 being released.

You should not manually install `open3d` if you are using a recent Slicer preview build. You should let the SlicerMorph extension install it for you when requested. I would suggest installing the latest Slicer Preview build as the one you currently have is about 2 months old now and also will get latest SlicerMorph.

I downloaded the new version, installed slicermorph and auto3dgm and then ran Alpaca and accepted the prompt for installing the open3d library and it hangs up and I get the following error in Python:

```auto

The problem originates due to a space located in the path (“Benjamin Colbert”) to the custom open3d-0.14.1 whl file that was installed. This space inappropriately leads it to be split into different arguments.

A quick workaround would be to relocate “C:/Users/Benjamin Colbert/AppData/Local/NA-MIC/Slicer/cache/SlicerIO/open3d-0.14.1+816263b-cp39-cp39-win\_amd64.whl” to “C:/open3d-0.14.1+816263b-cp39-cp39-win\_amd64.whl” and then do `slicer.util.pip_install(r"C:\open3d-0.14.1+816263b-cp39-cp39-win_amd64.whl")`.

I’ve improved the `pip_install` function so that it supports installing a downloaded wheel from a folder that has spaces in the name. The path either has to be quoted or provided as a list:

```auto
wheelPath = 'C:/Users/Benjamin Colbert/AppData/Local/NA-MIC/Slicer/cache/SlicerIO/open3d-0.14.1+816263b-cp39-cp39-win_amd64.whl'

# Option A: Quote the string (quoted strings are not split)
slicer.util.pip_install(f'"{wheelPath}"')

# Option B: Provide arguments as list (input argument is not split)
slicer.util.pip_install([wheelPath])

```

SlicerMorph needs to be updated accordingly - I’ve submitted a fix:

> <https://github.com/SlicerMorph/SlicerMorph/pull/206>
>
> Fixes the issue of pip\_install splitting up input wheel path at spaces.

Thanks Andras. This is now merged.
