To fix this, change the setting for file sharing implemnentations from gRPC FUSE to VirtioFS. If this doesn't work, it could imply a corrupted virtual environment. Build a new one and try again with that. This was what did the trick for me - but only for one deployment. Updating the few Python 3.8 lambda runtimes to 3.9 fixed it. The root cause could be from doing a keyboard interrupt during a deploy. Deleting existing images from within VS Code seems to have worked. ## Source [[MLE-213 - Add performance visualizations to trained model notification email#^h6heew|Source note]]
