Trying to train a ner model

[MagiCsito]

Hello,

I am trying to train a custom NER model and when I execute the command:

python -m spacy train 2023_config2_trf_gpu_v1_BEST_MODEL.cfg --output .\2023_NER_TA_sentences_v01 --paths.train .\train_2023_TA_sentences_v1.spacy --path.dev .\train_2023_TA_sentences_v1.spacy -g 0

I receive the following error:

The weird thing is that the command worked in the past, but I am trying right now and it doesn't work!
Could you help me?

Thank you

There is an error in your command, when you specify the path of the dev data you are writing --path.dev but it is --paths.dev with an s at the final of path
