[alexeigor]

Hey,

I got the same error after installing qnt locally with pip.
There is indeed a circular import in the current Github repo for the toolbox, introduced by this commit:
https://github.com/quantiacs/toolbox/commit/78beafa93775f33606156169b3e6b8f995804151#diff-89350fe373763b439e4697f9b11cceb811b4a3f0adc7a655707a936ce5646c01R6-R10
when some of the imports in output.py which were inside of fuctions before were moved to the top level.
Now output imports from stats and stats imports from output.

@support Can you please have a look?
