I keep running into this same error whenever I try to train a model based on samples I exported using the MaskRCNN metadata format. I ran this same workflow a couple years ago and was successful but i can't identify the issue now.</P><P>Any help parsing the error message would be greatly appreciated!</P> Thu, 12 Jun 2025 19:54:40 GMT https://community.esri.com/t5/arcgis-pro-questions/train-deep-learning-failure-with-maskrcnn/m-p/1623220#M96581 ColinBurchill1 2025-06-12T19:54:40Z https://community.esri.com/t5/arcgis-pro-questions/train-deep-learning-failure-with-maskrcnn/m-p/1624859#M96744 <P>The only thing I'm finding related to this error message is the following:<BR /><BR /><SPAN>Resolution: BUG-000160687 : "IndexError: index 0 is out of bounds for axis 0 with size 0" is returned when a space character exists in the training sample feature class' Classname attributes.</SPAN><BR /><SPAN>Workaround: Remove the space character from the training sample feature class' Classname attributes and re-run the Export Training Data For Deep Learning tool, followed by the Train Deep Learning Model tool.</SPAN><BR /><BR /><SPAN>BUG-000160400 : Error 999999 is returned when running the Export Training Data For Deep Learning tool with an input mask polygon.</SPAN><BR /><SPAN>Workaround: Leave the Input Mask Polygons parameter empty before running the tool or specify an extent under Environments tab &gt; Processing Extent.</SPAN></P> Wed, 18 Jun 2025 21:56:56 GMT https://community.esri.com/t5/arcgis-pro-questions/train-deep-learning-failure-with-maskrcnn/m-p/1624859#M96744 Robert_LeClair 2025-06-18T21:56:56Z https://community.esri.com/t5/arcgis-pro-questions/train-deep-learning-failure-with-maskrcnn/m-p/1625432#M96781 <P>I appreciate your input! After a bit more testing we found that it was the space character in our Classname that was causing it to fail.&nbsp;</P> Fri, 20 Jun 2025 18:49:39 GMT https://community.esri.com/t5/arcgis-pro-questions/train-deep-learning-failure-with-maskrcnn/m-p/1625432#M96781 ColinBurchill1 2025-06-20T18:49:39Z
