Hi, I encountered the error described in the title of this issue, while trying to run the gpt-2 example. Here is my command:

export CUDA_VISIBLE_DEVICES=7
torchrun --nnodes=1 --nproc_per_node=1 --rdzv_id=1 --rdzv_backend=c10d --rdzv_endpoint=localhost ./gpt2_test.py \
    --model gpt2-base \
    --save-dir results/gpt2-prune \
    --data-path ... \
    --cook-config configs/gpt2-prune.json \

It seems that this is an error within the package bmtrain, so could you help figure out what happened or how to avoid it? Thanks a lot!

Sorry for the delay! This is probably a CUDA version mismatch, so you'd better check it. Generally, CUDA 11 will work normally.

my cuda version is 11.7 and I'm still suffering this issue. Why insist on using this annoying package bmtrain?

I also encountered this problem, link https://github.com/OpenBMB/CPM-Bee/issues/18, and it can not reslove.
