Issue with band calc -
Closed this issue · 2 comments
I'm having problems with Band Calc, in fact, it could be a problem with Python. The script starts to calculate and gives an error, which is below.
Um erro ocorreu enquanto executava o código Python:

Hello, it could be an issue related to input data.
Please copy the log file following these steps https://semiautomaticclassificationmanual.readthedocs.io/en/latest/faq.html#how-can-i-report-an-error
I'm closing this because of the new version 8 of SCP.
Please reopen it if it is still relevant in the new version.
Thank you!
