No module named 'pt'

[LSnyd]

Hi there,

I am trying to get the cifar10 example running with Federated Learning.

I followed all the steps mentioned here https://nvidia.github.io/NVFlare/quickstart.html and then uploaded and deployed the app from the admin terminal. When I am trying to start the app, I am getting the following error:

./run_1/app_server/config/config_fed_server.json in JSON element components.#5: No module named 'pt'

Event though, in the run_1 folder of the clients is a folder called pt with the specified learners. Do I have to configure the path to the custom folders somewhere?

Hello, thank you for trying out the example. There are several ways to make custom code available to clients when using nvflare. Most hello-* examples follow the approach described in the getting started guide using a custom folder within your FL application. Note that using a custom folder in the app needs to be allowed when using secure provisioning. By default, this option is disabled in the secure mode. POC mode, however, will work with custom code by default.

In contrast, the CIFAR-10 example assumes that the learner code is already installed on the client's system and available in the PYTHONPATH. Hence, the app folders, don't include the custom code there. The PYTHONPATH is actually set in the run_poc.sh or run_secure.sh scripts of the example. Running these scripts as described in the README will make the learner code available to the clients.

Hi @LSnyd, were you able to resolve the issue?

Hi @holgerroth, thanks so much for the clarification and sorry for my late reply, I had to prioritize a different project. However, I got the FL Training running today. For now it just runs and does not perform well yet. Therfore I have more questions, but I will open different issues for those :)
Thanks for your help!

This has worked for me, I just have to read the documentation deeply
