AttributeError: module 'scipy' has no attribute 'spatial'

**Describe the bug**
I am using Python 3.8.13 and installed pyFlowSOM as explained here: https://pypi.org/project/pyFlowSOM/.
The module is giving me a basic error: _AttributeError: module 'scipy' has no attribute 'spatial_'
I anticipated a normal return of the output. Since it is written in C, I cannot locate/debug the code. Even if someone can guide me where to explore, it would be a help.

**To Reproduce**
I ran the following code:

`node_output = som(data, seed = 30)`

Note that the data was a 2D numpy array.

The following error was encountered:
