TypeError: let_bind() got an unexpected keyword argument 'error_map'

I just installed deepspeec-server using a fresh virtualenv in debian testing

I get this error:

$ deepspeech-server --config config.json

can you try upgrading rx to 1.6.1 ? not sure but this may be the cause of the error.

That's it! Upgrading 1.6.1 solved the issue.

I have identical pip list and rx==1.6.1 from pip install -r requirements.txt but still have this error
