Collecting pyzmq==18.1.0
Using cached pyzmq-18.1.0-0_py38h16f9016-cp38-cp38-win_amd64.whl (17.8 MB)

ERROR: pyzmq has an invalid wheel, multiple .dist-info directories found: pyzmq-18.1.0.dist-info, libsodium-1.0.17.dist-info

Looks like you have a bad cache.

assume i understand you correctly, i open requirements.txt file and remove this package, so all other packages installed very well, and i install this package of version pyzmq-18.0.0 , so it's installed correctly, i also try in other python versions , the same

Try pip install --no-cache-dir -r requirements.txt

Unfortunately, the same error pop up

Hmm, I just tried bumping our CI to python 3.8. It installs just fine.

Perhaps try creating a conda environment or a new virtual env.

mkdir ~/venv
virtualenv --python=python3 ~/venv
source ~/venv/bin/activate
cd ~/ParlAI
pip install -r requirements.txt

the issue solved by :
pip install --no-binary=:all: pyzmq==18.1.0
