Hi Chris, I’m finding that when I launch a workspace file with MWClient, sometimes it looks like the Python Client Bridge script runs before the MWEL is done loading, and so it doesn’t initialize properly. I think you fixed some race like this before, is that right? I’m using the snapshot from 2021.01.08. Mark ---

Hi Mark, Yes, when loading a workspace that contains an experiment path, the client doesn’t wait for the experiment to finish loading before launching the Python bridge or any other plugin window. I don’t think this issue has come up before, which is surprising. I will work on fixing this. In the meantime, you may be able to avoid the issue by adding a short wait at the start of your Python bridge script – maybe a second or two, depending on how long your experiment takes to load. Sorry about this! Cheers, Chris ---

Thanks, Chris! I have a strong feeling that you and I discussed this before, but perhaps my memory is broken on this. I think I’m overfilling it. Mark ---

Hi Mark, I’m looking at this now, and I’m having trouble understanding where this is causing problems for you. Can you tell me exactly how the script’s initialization fails? Is it expecting a particular value for a variable and not seeing it? Thanks, Chris ---

Hi Chris, I saw this with the following: An experiment that takes longer to load than the Python bridge script takes to register callbacks on variables. The error I got looked to be something like ‘variable missing’. Any chance you can see this if you use an expt that takes a long time to load? ---

Hi Mark, I still can’t reproduce this. Even if I try to register a callback for a non-existent variable, I never get an error message (which isn’t a great outcome, obviously, but beside the point here). Can you send me an example experiment and Python script that have produced this issue? I don’t necessarily need to be able to run them. I mainly want to see how you’re setting things up, as there may be relevant details that I’m missing. Thanks, Chris ---
