Failed to reproduce the notebook example

[jpzhangvincent]

I followed the installation instruction and this notebook example on my Mac M1 max laptop. But I failed at running clip-retrieval inference --input_dataset image_folder --output_folder embedding_folder(even with the absolute path)

Here is the error trace

The number of samples has been estimated to be 3
