Changes in imported arcPy modules

Question

Hi,

when using imported modules and one of the modules changes, ArcGIS PRO does not reflect that change, but runs the old version. it seems to cache it somehow.

the only way to get the changes to run is to restart PRO.

py script 1 that is actually run via toolbox:

import myFile

myFile.runCode()

py script 2 that is imported:

def runCode():
   import arcpy
    arcpy.AddMessage('change me!')

Is there a way around this?

Any input welcome!

Matt

This was really close but didn't work for me. This worked - hope it helps someone as frustrated as I was 🙂

As Joshua point out, do read the fine print. I generally do the reload from the command line should I need to edit a script that has been imported. Should you feel the need to include it in a script, you must remember to comment the reload line(s) before your final commit. It is also a simpler idea to simply delete references to the imported module(script) and its imports while you are editing.. del my_imported_module In fact, get used to using your builtins... in this example I cleaned out the 'fluff', found what is currently been loaded, imported a module (aka script), deleted it then examined if it was still around >>> locals().keys() dict_keys(['__builtins__']) >>> import find >>> locals().keys() dict_keys(['find', '__builtins__']) >>> dir(find) ['__all__', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__private__', '__spec__', '_demo', '_func', '_large', 'dedent', 'find', 'ft', 'np', 'script', 'sys'] >>> >>> del find >>> locals().keys() dict_keys(['__builtins__']) >>> ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ So, you really don't need any form of reloading, if you understand the command line.

I am glad you got it working.  I highly recommend you read the documentation on importlib.reload() .  As powerful and handy as reload() is, there is some fine print with its use.  Without understanding the nuances and caveats of using it, you could get yourself wrapped around an axle at some point.
