Can you share the env? What command did you execute to get this output?

[KhinChoWin-AI]

The env is as follows:
name: base
channels:

• defaults
  dependencies:
• conda
• python=3.9
• conda-env
• conda-build
• conda-verify
• _ipyw_jlab_nb_ext_conf
• anaconda==2022.05=py39_0
• anaconda-navigator
• navigator-updater
• pillow
• cudatoolkit=11.2
• cudnn=8.1.0
  prefix: /home1/ai20resch16001/anaconda3

The command is python -m cli clup
./models/target/pretrained/swav-1000ep-FER2013-5000prototypes.ckpt
./models/source/resnet18_rafdb.pt

--labeled_samples_size 0.3

From this I am not sure I can check the list of packages installed. Did you follow the instructions to install? Did you then also source the venv? Just making sure before moving on with other possible causes.

[KhinChoWin-AI]

Yes, I also followed the same stepup that you mentioned using .venv.

Have you tried other commands? Is this the only one that does not work? Can you confirm the two args pointing to model weights link to existing files?
