Any idea what could be going wrong here?
Hi, I think it's because this RMSNorm is being set to None https://github.com/HazyResearch/based/blob/e8de5648f7e84248be8ebc1499e817641b0f577b/based/models/gpt.py#L371
Due to the import structure here: https://github.com/HazyResearch/based/blob/e8de5648f7e84248be8ebc1499e817641b0f577b/based/models/gpt.py#L52
The options are to
- install the norm from flash attention here: https://github.com/Dao-AILab/flash-attention/tree/main/csrc/layer_norm
- set it to import RMSNorm from here: https://github.com/HazyResearch/based/blob/master/based/ops/triton/layer_norm.py, by uncommenting this line: https://github.com/HazyResearch/based/blob/e8de5648f7e84248be8ebc1499e817641b0f577b/based/models/gpt.py#L57
Sorry for the difficulty -- we will fix the install / instructions for this
No worries, and thanks for the speedy reply. Your guidance helped me get past the above error by installing the norm from flash-attn, but there seem to be more undocumented dependency issues:

if fused_bias_fc and FusedDense is None: raise ImportError("fused_dense is not installed")
ImportError: fused_dense is not installed
I'm a little baffled, since it seems like FusedDense is being imported from flash_attn here:
https://github.com/HazyResearch/based/blob/e8de5648f7e84248be8ebc1499e817641b0f577b/based/models/mixers/slide_attention.py#L29
Are there additional subpackages within flash-attn that need to be installed?
For reference, here is my updated dockerfile:

That line you pointed out requires this to be installed: https://github.com/Dao-AILab/flash-attention/tree/main/csrc/fused_dense_lib
Would recommend cloning flash-attention and python setup.py install within this directory An alternative workaround, without the install, is to, in the config, set fused_bias_fc = False
After some tweaking, I think I've got it working. I ended up using the HazyReasearch/flash-attention fork. For others trying via docker, this is the dockerfile I used:

Hi! I got a similar problem while running the sample code:

tokenizer = AutoTokenizer.from_pretrained("gpt2")
model = GPTLMHeadModel.from_pretrained_hf("hazyresearch/based-360m").to("cuda", dtype=torch.float16)
input = tokenizer.encode("If I take one more step, it will be", return_tensors="pt").to("cuda")
output = model.generate(input, max_length=20)
print(tokenizer.decode(output[0]))

Is this due to code changes 2 days ago or I am missing some steps?
yes that was due to the changes, please try again and let me know if you run into issues
