Issues with Docker and help needed

[MaitreyiJ]

Hi !
I have been trying to run spyKingCircus through the docker wrapper.
Initally I did not face any issues with running it in the container.
But recently I have been facing this issue
Traceback (most recent call last):
File "C:\Users\Maitreyi\CareerDevelopmentoversumeer\SummerResearch2020\spikeforest2\kachery\example_mountainsort4.py", line 12, in
result = sorters.mountainsort4.run(
File "C:\Users\Maitreyi\CareerDevelopmentoversumeer\SummerResearch2020\spikeforest2\kachery\hither_sf_core.py", line 271, in run
_run_job(job)
File "C:\Users\Maitreyi\CareerDevelopmentoversumeer\SummerResearch2020\spikeforest2\kachery\hither_sf_core.py", line 449, in _run_job
returnval, runtime_info = run_function_in_container(
File "C:\Users\Maitreyi\CareerDevelopmentoversumeer\SummerResearch2020\spikeforest2\kachery\hither_sf_run_function_in_container.py", line 263, in run_function_in_container
raise Exception('Non-zero exit code ({}) running [{}] in container {}'.format(retcode, label, container))
Exception: Non-zero exit code (127) running [mountainsort4] in container docker://magland/sf-mountainsort4:0.3.2

I am trying to benchmark my algorithm with all these standardized algorithms and I am finding spike forest super helpful, but I dont know why I am suddenly having this error.
