TypeError: descriptor 'union' of 'set' object needs an argument when generate protein embedding

[zhuojiuqingyun]

Dear authors, Thank you very much for making this great tool. I got the following error while running Generate Protein Embeddings.ipynb using my protein fasta.

!python map_gene_symbol_to_protein_ids.py \
    --fasta_path ./data/{NAME}.fa \
    --save_path ./data/{NAME}.gene_symbol_to_protein_ID.json

!python convert_protein_embeddings_to_gene_embeddings.py \
    --embedding_dir ./data/{NAME}.clean.fa_esm2 \
    --gene_symbol_to_protein_ids_path ./data/{NAME}.gene_symbol_to_protein_ID.json \
    --embedding_model ESM2 \
    --save_path ./data/{NAME}.gene_symbol_to_embedding_ESM2.pt

I didn't encounter this error when I running the example Xenopus_tropicalis. Could you help me with my issue?

Yours sincerely. Ruijie

Please double check and make sure the path is correct:

FileNotFoundError: [Errno 2] No such file or directory: 'data/xenia.proteins.gene_symbol_to_protein_ID.json'

The error is due to no file existing at that location.

Thanks for your reply. In fact, it's this error which led to data/xenia.proteins.gene_symbol_to_protein_ID.json not being generated. TypeError: descriptor 'union' of 'set' object needs an argument I think the reason is that I couldn't find the protein fasta from ensembl, so I downloaded from NCBI. So my protein fasta description doesn't contain gene symbol and protein id ,which caused the error above. How can I generate protein embedding from protein fasta not downloaded from Ensembl? Could you give me some instructions?

Thanks a lot!
