Is it possible to do inference on the aforementioned machines as we are facing so many issues in Inf2 with Falcon model?
Context:
We are facing issues while using Falcon/Falcoder on the Inf2.8xl machine. We were able to run the same experiment on G5.8xl instance successfully but we are observing that the same code is not working on Inf2 machine instance. We are aware that it has Accelerator instead of NVIDIA GPU. Hence we tried the neuron-core's capability and added required helper code for using the capability of neuron-cores of the instance by using the torch-neuronx library. The code changes and respective error screenshots are provided below for your reference:
Code without any torch-neuronx usage - Generation code snippet:
Can we try Llama 2 on G4dn.8xLarge and Inferentia 2.8xlarge instances or it is not supported yet? If not, which machine instance we should try considering cost-effectiveness?
Is it feasible to do inference with Falcon on Inf2 or should we go for G4dn.8xlarge as we are facing so many issues in Inf2?
Hi all,

Code using torch-neuronx - helper function code snippet:

Can this github issue address our specific problems mentioned above? https://github.com/oobabooga/text-generation-webui/issues/2260
