Hi all,

I am trying to run some 3D morphometrics on ALPACA (a program within slicermorph) and every time I try to run it, it tells me “ALPACA requires open3d library. Installation will take a few minutes” then a whole installation sequence takes place in python. However, I keep running into this error and I am not sure how to remedy it.

I appreciate any help possible and thank you in advance.

Thanks @Khanine, we are updating the ALPACA module to use a more recent version of the open3d library to correct this issue. The new version should be available tomorrow through the extension manager, or later today if you’d like to update it manually.

@Khanine The fix is up on the SlicerMorph repo and you should be able to update it through the extension manager tomorrow. You can also correct it in your installation by running the following line in the Python Interactor:

```auto
pip_install('pywinpty==1.1.6')

```

and then opening the ALPACA module.

Hi! i have a similar problem, but in my case the error is:

The line pip\_install(‘pywinpty==1.1.6’) doesn’t work for me.

I’m new to slicermorph and thanks in advance for any help

This was only needed for Slicer 4.11.2021026.

> [@Sebastian\_Rodrigo\_Ag](#):

> Slicer 5.1.0-2022-05-01

Since you are using recent Slicer preview, you should be able to skip that step. Did you attempt this because you ran into a problem using latest Slicer Preview? Or were you just following some older instructions?

@Sebastian_Rodrigo_Ag could you try running these lines from the Python Interactor?

> wheelPath = ‘C:/Users/Sebastián Aguayo/Documents/3D Slicer/open3d-0.14.1+816263b-cp39-cp39-win\_amd64.whl’

Hello Sara, first of all thank you very much for the answer. I entered the code and it sends me this error:

> > > wheelPath = ‘C:/Users/Sebastián Aguayo/Documents/3D Slicer/open3d-0.14.1+816263b-cp39-cp39-win\_amd64.whl’

> > > wheelPath = ‘C:/Users/Sebastián Aguayo/Documents/3D Slicer/open3d-0.14.1+816263b-cp39-cp39-win\_amd64.whl’  
> > > ^  
> > > SyntaxError: invalid character ‘‘’ (U+2018)  
> > > pip\_install([wheelPath])  
> > > Traceback (most recent call last):  
> > > File “”, line 1, in   
> > > NameError: name ‘wheelPath’ is not defined

maybe it’s because of the “´” in Sebastián

I have corrected the issue causing the filename bug in the most recent version of ALPACA, could you try updating?
