anaconda exit1 에러 해결방법

Thanks for filing this issue.
Looks like zmq package is no longer working as expected. Possible you updated this or some other package or the python environment accidentally that caused this issue.

Please could you try to re-install ipykernel as follows:
conda install ipykernel --update-deps
if that doesn't work then try
conda install ipykernel --update-deps --force-reinstall
