Error Message: Error writing to output stream. (when using Idle Python GUI)
Solution: Imatest IT writes output to your computer’s standard output. This error occurs when Idle is launched as a standalone GUI app without a connected terminal (i.e., launching from the Start Menu in Windows, or using the “idle &” command in Linux).
To fix this error, you need to launch Idle from the command line.
|Windows:||cd “C:\Program Files\Imatest\v4.5\IT\samples\python\”
Once Idle is opened with the example script, you should now be able to run the module (F5).
