ValueError: attempt to get argmax of an empty sequence

[nitinmukesh]

Any suggestions how to fix this issue
I am using the default provided with the repository, only updated the following in \TokenFlow\configs\config_pnp.yaml

batch_size: 8
to
batch_size: 1

data_path: 'data/woman-running'
to
data_path: 'data/woman-running.mp4'

(tokenflow) C:\tut\TokenFlow>python run_tokenflow_pnp.py --config_path "configs/config_pnp.yaml"
A matching Triton is not available, some optimizations will not be enabled

1. I tried the solution mentioned here still the same issue
   Tried to build a colab notebook, but got "ValueError: attempt to get argmax of an empty sequence" when running "!python /content/TokenFlow/run_tokenflow_pnp.py" #17

2. I also tried downloading the file mentioned in PR, still does not work
