Error in running python example (synthesize_dataset.py)

[christopherhitz]

Hi,

I have problems running the Python example synthesize_dataset.py from the mountainsort_examples.
I use Anaconda with the Spyder environment setup and run the example file with the command
synthesize_dataset('/home/chris/Documents/dataset0000/',M=4,duration=60,average_snr=7,K=20)
While debugging, Python enters the function, and runs line 12ff
mlp.addProcess('ephys.synthesize_random_waveforms', ...
Then, in line 27ff,
mlp.addProcess('ephys.synthesize_random_firings', ...
the debugger stops with the error message
AttributeError: 'NoneType' object has no attribute 'addProcess'

Thus, the problem might be an wrongly installed package. Here is how I did the installation:

1_ Install MountainLab as indicated in
https://github.com/flatironinstitute/mountainlab-js
using the conda commands in the Ubuntu terminal.

2_ Install MountainSort as indicated in
https://github.com/flatironinstitute/mountainsort_examples/blob/master/README.md
using the conda commands in the Ubuntu terminal as well.

These installations seemed to run smoothly.

2_ Additionally, I installed from
https://github.com/flatironinstitute
/ qt-mountainview
/ mountainsort_examples
and
/ ephys-viz

Every package seemed to be installed fine.

Maybe someone has some ideas. I think, that it is an easy problem, if you are experienced with Ubuntu or Linux in general.

Best,

Chris
