And the folder is like:
SimplerEnv-main-octo-docs
SimplerEnv-main-octo-examples
SimplerEnv-main-simpler_env-main_inference.py
SimplerEnv-main-octo-octo-model-octo_model.py,this is the py file quoted by the "octo_model" py file which is quoted by the main_inference.py:
try:
from simpler_env.policies.octo.octo_model import OctoInference
except ImportError as e:
print("Octo is not correctly imported.")
print(e)

I think you forgot to cd octo/; pip install -e .

Please follow the instruciton in the Octo inference setup in README (it also requires installing jax)

I am sure I have done this all,the "pip install -e ." result is:
Successfully built octo
Installing collected packages: octo
Successfully installed octo-0.0.0

but still the error
