No module named 'nvflare.lighter.impl.auth_policy' #16

Open hwpang opened 3 weeks ago

hwpang commented 3 weeks ago

Hi,

Thanks for the great demo! I am following the instructions for the federated learning at https://github.com/hwpang/medical-imaging/blob/main/federated-learning/README.md.

I was able to follow through until provision -p project.yml step, where I encountered the following error:

Project yaml file: /home/runner/medical-imaging/federated-learning/project.yml.

Unable to handle command: provision due to: No module named 'nvflare.lighter.impl.auth_policy' 

sub_parser is: ArgumentParser(prog='nvflare provision', usage=None, description=None, formatter_class=<class 'argparse.HelpFormatter'>, conflict_handler='error', add_help=True)
usage: nvflare provision [-h] [-p PROJECT_FILE] [-w WORKSPACE] [-c CUSTOM_FOLDER] [--add_user ADD_USER] [--add_client ADD_CLIENT]

options:
  -h, --help            show this help message and exit
  -p PROJECT_FILE, --project_file PROJECT_FILE
                        file to describe FL project
  -w WORKSPACE, --workspace WORKSPACE
                        directory used by provision
  -c CUSTOM_FOLDER, --custom_folder CUSTOM_FOLDER
                        additional folder to load python codes
  --add_user ADD_USER   yaml file for added user
  --add_client ADD_CLIENT
                        yaml file for added client

I would appreciate any advice on how to modify the config file to make it work for newer version of NVFLARE. Thanks!

I was able to get this to work after swapping it to the default provision file generated by the newest nvflare. However, I encounter other problem. I am following step 4 in the federated learning demo to prepare clients: https://github.com/hwpang/medical-imaging/blob/main/federated-learning/README.md#4-prepare-clients. I run into the following error. Would appreciate any advice on how to resolve this.
