@shamanez  
I just wanted to know in rag-end2end retriever I want my architecture to be t5-based!  
using  
– model\_path t5-small  
–model\_type t5

still there is some error saying:  
File “/home/ec2-user/SageMaker/transformers/examples/research\_projects/rag-end2end-retriever/lightning\_base.py”, line 279, in on\_sanity\_check\_start  
pl\_module.model.rag.retriever.init\_retrieval() # better to use hook functions.  
File “/home/ec2-user/anaconda3/envs/python3/lib/python3.10/site-packages/torch/nn/modules/module.py”, line 1269, in **getattr**  
raise AttributeError(“‘{}’ object has no attribute ‘{}’”.format(  
AttributeError: ‘T5ForConditionalGeneration’ object has no attribute ‘rag’

For this, you might need to play around with the rag\_modelling.py
