LM 3.1.0 compatibility with ArcGIS Pro 3.5.3?

[Amy Weckle]

When I add the LM 3.1.0 .tbx to my project in ArcGIS Pro 3.5.3 and try to run it, I get this error:

  Traceback (most recent call last):  File "C:\Users\aweckle\Downloads\linkage_mapper_3_1_0\linkage_mapper_3_1_0\toolbox\scripts\lm_master.py", line 160, in <module>  if cfg.STEP3: ^^^^^^^^^^^  File "C:\Users\aweckle\Downloads\linkage_mapper_3_1_0\linkage_mapper_3_1_0\toolbox\scripts\lm_master.py", line 30, in lm_master  Called by ArcMap with parameters or run from command line with parameters  ^^^^^^^^^^^^^^^ AttributeError: 'Configure' object has no attribute 'PARAM_NAMES'

Hi Amy,

Try getting rid of spaces and parentheses in your tool path and let me know how that goes?

Thanks,

John
