I tried this code and am getting an error. Yet, while the first ‘long-running’ cell keeps running, you are able to run the other ‘normal’ cells. The output from the first cell stays isolated in the first cell as it continues to run and doesn’t pollute elsewhere. This is working in my tests in the classic notebook interface and JupyterLab. Multiprocessing.Process(target=network_call).start() If there are any pointers that could be given to me, me would be very grateful for receiving them.Better approach to try, running the long running cell in a multiprocessing process, see Python 3 Module of the Week: multiprocessing – Manage processes like threads.įollowing your posted example, you’d run: # Long running cell That was me trying to nohup my subprocess and disconnect from all my buffers, but I guess it's not working because the images are not downloading. dumps ( for d in data if d is not None ]), 'Bandcamp' ], stdin = None, stdout = None, stderr = None ) Popen ( [ 'nohup', '/usr/bin/python3', '/Users/danluba/PycharmProjects/AlfredMusicSearch/images.py', '&' ,

fork () if pid > 0 : # return results to alfred on main process Here's the money shot in the rough code I've written so far, just to try and get my head around things: For example, he talks about nohupping (one of the new things for me), and I genned up on what that is, but I can't see where he does that in that script. I have a basic idea of what I am trying to do, but all of my attempts are failing, and I can't really understand why doing the things he's doing. There's a lot of new stuff in there for me. I've spend the best part of the day (or the worst part of the day, depending on how you look at it) trying to get Alfred to exit the script, leaving the download threads doing their thing in the background and displaying the results, sans images, so that I can get the script to rerun and bind to the downloaded images periodically, thereafter.Ĭan someone explain to me how this can be done? How can I get my main script to quit, leaving the background processes to download the images on the sly? Probably the safest thing to do is explain it to me like I'm five years old.

I have the downloads being done concurrently, using asyncio - my problem is that Alfred is waiting for all of my subprocesses to finish before it exits the main script. I have that working now, but it's taking five to ten seconds to download all of the images. I would like to include the cover art in these results.

I'm currently writing a workflow that searches music stores for a query and returns a list of results you can select from to open the corresponding URL.
