model/coherencemodel.py issue - no single core mode

[chriswi93]

Description

model/coherencemodel.py can not be used in single core mode.

Steps/Code/Corpus to Reproduce

line 218
self.processes = processes if processes > 1 else max(1, mp.cpu_count() - 1)

Expected Results

If I choose processes parameter = 1 for TopicCoherence, self.processes should be 1, too.

Actual Results

If I choose processes parameter = 1 for TopicCoherence, self.processes is mp.cpu_count() - 1. In my case self.processes = 3.

Solution

line 218
self.processes = processes if processes >= 1 else max(1, mp.cpu_count() - 1)
