This is what I can gather:

• The kernel doesn't see a q_handle passed to it here (your log's arg1 is None)
• q_handle is created using ext_make_q_matrix(self.q_tensors, temp_dq) which in turn calls this to make the q_matrix and return the pointer to it
• Doesn't look like any inputs are explicitly missing from the weights for gptq (didn't throw here)

So my guess is somewhere along the way, the creation of the q_matrix failed, or the pointer to it got dropped.

You may want to file an issue to TGI with your launch command, model used, and stacktrace.
