How to resolve 'Could not find evo2_7b.pt or any of its shards in /root/.cache/huggingface/hub/models' error

[ywxk947]

Thanks for putting out a great DNA model!
I'm hoping someone can help me with an issue I'm facing while installing the Evo2 model. The initial installation steps seemed to complete without any problems. However, when I run the command to test the installation, I encounter an error.

The command I'm using is:

bash
python -m evo2.test.test_evo2_generation --model_name evo2_7b
This results in the following error message:

[09/03/25 21:59:19] WARNING transformer_engine.pytorch.attention.dot_product_attention.utils - WARNING - Supported flash-attn versions are >= 2.7.3, <= 2.7.4.post1. Found backends.py:98

It seems the script is looking for a file named `evo2_evo2_7b.pt, but it cannot find it in the Hugging Face cache directory, leading to a FileNotFoundError.

Could anyone kindly guide me on how to resolve this issue?

Thank you very much for your help.
