We were trying to finetune a Matformer checkpoint ( MatFormer-OLMo-180M Link )
We used the following command to call the training script
python train.py ../configs/pile-tiny.yaml \
--matformer_factor=8 \
--matformer_factor=8 \
--model.d_model=512 \
--model.n_heads=16 \
--model.n_layers=8 \
--model.max_sequence_length=2048 \
--device_train_microbatch_size=8 \
--global_train_batch_size=128 \
--max_duration=75000 \
--optimizer.learning_rate=1.0e-3 \
--console_log_interval=10 \
--load_path=:"/raid/ganesh/namitha/Skill_localization_experiment/ckpt_paths/MatFormer-OLMo-180M" \
--run_name="matformer-olmo-180M-finetune"
where the folder mentioned in load_path is obtained by download from the link mentioned in the README for MatFormer-OLMo-180M .
However running this gives us the following error
[2024-04-18 09:09:04] CRITICAL [root, rank=0] Uncaught ValueError: Must flatten tensors on the same device but got both cuda:0 and meta
