Hi @MKamyab1991,

Can you provide more details about your installation?
Did you pip install, or are you building from source?
What version, or commit of garage are you using?

[Kamyab-Majid]

Thanks for the response. I used the pip and the garage version is garage-2021.3.0
this is the full error :

ImportError Traceback (most recent call last)

I have the exact same problem. I tried installing using pip and building from source and both ran to the above error.

Just copy the package in your project or fix it manually. I think they are busy with other issues :).

Just looked into this.

We moved TFTrainer to the base of garage, so you can now import it by calling
from garage import TFTrainer

Sorry for the slow replies. At the moment many of our students are on summer vacation, and so only there will only be 2 active maintainers till mid August.

@MKamyab1991 could you go ahead and try this fix out? If it works for you, could you please open a PR?

Thanks,

I used the examples in the garage documentation and as it looks like they're not updated cause TFtrainer is no longer under experiment module and has moved to trainer module. The examples in the git are updated though.
