Welcome,
Before sending an email to the group:
Please read
Frequently Asked Questions
Make sure you read the
Tesseract documentation
Search internet sources (including this group) for a solution
If you have a problem:
Provide all steps (including input resources) for its replication.
So not send a screenshot of the terminal - send the logs or copy text from a terminal.
