Problem moving module RecordSensor

Engineering NuPIC
1

I’m trying to rename some regions, specificially:

renamed:    src/nupic/regions/RecordSensor.py -> src/nupic/regions/record_sensor.py

But I get this error now when I run a test:

> python tests/unit/nupic/docs/examples_test.py
WARN:   PyRegion::createSpec failed: 0x7fff5168b9d8

So what exactly happens when this is called?

n.addRegion("sensor", "py.RecordSensor", json.dumps(dict(verbosity=sensorParams['verbosity'])))

If I change py.RecordSensor to py.record_sensor, I get a different error:

RuntimeError: Matching Python module for record_sensor not found.

@scott Are there nupic.core changes that need to be made in order to change region module names?

The region registration in the network api currently requires the module and class names to match. I’d like to remove that limitation soon.

Ok, in the meantime, I won’t do snake_case refactoring in regions.
