Batchalign 2 - Unable to run Whisper Engine / Forced Alignment

['Richard Ghiuzan' via chibolts]

Dear All, 
I have been using the library version of Batchalign 2 to produce 
transcripts, and while I've been able to do so, I've been getting a 
recurrent error whenever trying to run a forced alignment on an existing 
transcript using the following line of coding:
 
chat = ba.CHATFile(path = "inputfile.cha")
doc = chat.doc
nlp = ba.BatchalignPipeline.new("fa", lang="eng", num_speakers=2)
doc = nlp(chat)
final = ba.CHATFile(doc=doc)
final.write("final.cha")

I get a very lengthy error output, which I can share if needed, but this 
seems to be the main error:
RuntimeError Traceback (most recent call last) Cell In[38], line 4 2 chat = 
ba.CHATFile(path = "inputfile.cha") 3 doc = chat.doc ----> 4 nlp = ba.
BatchalignPipeline.new("fa", lang="eng", num_speakers=2) 5 doc = nlp(chat) 6 
final = ba.CHATFile(doc=doc)

[...]

2572 raise ValueError( 2573 "You cannot cast a GPTQ model in a new `dtype`. 
Make sure to load the model using `from_pretrained` using the desired" 2574 
" `dtype` by passing the correct `torch_dtype` argument."

Would anyone have encountered a similar error and know how to solve it? 
Thank you in advance for the time and availability. 
Kind Regards, 
Richard
