sequence_inference error

[Albert-Shuai]

Hi:

I am trying to do sequence_inference based on a trained model, while the following error occurs:

I am not sure how I shall change my code to make it work. May I ask for your suggestions? Thanks!

Hi. I tried it on different computers, while all of them reported the same error, so I am wondering what I can do to that.

FYI, I am using Sample_Inference under DeepTCR_WF

[Albert-Shuai]

And a toy code I am using is like the following:
seq = np.array(['CASSASS','CASSASSA','CASSASSS'])
sample = np.array(['s1','s1','s2'])
DTCR_WF.Sample_Inference(sample_labels = sample, beta_sequences=seq)

And it will return None, instead of a matrix as described

If you want to do sequence inference with the repertoire model, you should not provide a sample label. It should left as None.

[Albert-Shuai]

If you want to do sequence inference with the repertoire model, you should not provide a sample label. It should left as None.

Thanks! But what if I want to predict the label of a sample? Shall I use Sample_Inference()? If so, why this method returns None?

[sidhomj]

Because the sample predictions are in the object. Please read the documentation. It explains everything.

Thanks so much for the response, and sorry for the stupid question. I though it would return an array like what sequence_inference did, while it is stored inside the object.
