Issue using Random Forest initialization

Hello,

 

The SM Machine learning process is unable to solve the random forest initialization. I'm running Imagine 16.5.0 build 1265

 

The same model run with no issue on the same machine with the native 16.5 Imagine version

 

Was there any change on the expected machine configuration since the last Imagine version ?

 

Regards,

Re: Issue using Random Forest initialization

There is no change in system requirements among ERDAS IMAGINE 16.5, ERDAS IMAGINE 16.5 Update 1 and ERDAS IMAGINE 16.5 Update 2.

Re: Issue using Random Forest initialization

Hi Sam

 

 

Thanks for your response. I've tested the script on two PC and obtained the same result. The initialization failed. However, I managed to run the same script with no issue in April 2018. I think something has been changed in the reading of the shape format specifications.
