I know when there are some errors in the code it will become yellow, but sometimes it still keeps yellow even I have fixed the errors.

Revise.jl will change the color of the prompt if it finds an error that prevents it from working. Unfortunately this is not documented at all :expressionless:

It usually also shows a warning indicating that it’s a revise problem, and that you should try running Revise.retry(). Though I don’t know why that doesn’t appear in this case.

Thank you! Although nothing has changed after I ran Revise.retry() :handshake: :grinning:

There are a few reasons is can stay yellow, one is if you switched to another REPL mode when it was fixed. Similarly, if you enter another REPL mode and a revise error occurs that mode can become yellow instead. Once this mixup has occurred, it has to be manually fixed or the Julia REPL restarted.

Oh, so it is! Thank you very much! :handshake:

But I’m not ready to restart the REPL for quite some time, because there is
important data in it that I haven’t found a proper way to save… :smiling_face_with_tear:

I have heard it can be unreliable, but JDL2.jl has worked fine for me for short-term data storage: save variables to file, restart REPL, load variables from file, continue.

Yes, I’m aware of it. thanks! But unfortunately, I have been just faced with a situation that it can’t save&load a trained model successfully. :woozy_face:
