T5 submission fails on OpenLLM leaderboard

T5 model submissions do not work in OpenLLM leaderboard. When I ran LMEH with the option --model hf_causal on my local machine, it gives the following error (see SS). But it seems to work fine with the option --model hf_seq2seq. However, in the leaderboard submission, there is no way to change the option to mention it is a seq2seq model. What is the solution? @valhalla @SaylorTwift ?
