Hi,
Thank you for your feedback, I have updated the pip install instruction to use http instead of ssh, which should work now. I will also update the dummy package in Pypi as soon as I can (but not a lot of time to do this in this period of year ;) ) which will make installation simpler (pip install nevergrad).

Concerning your second issue, it does strongly look like a path issue. Are you sure you are using the same install in both cases ?
I would advice trying in a virtualenv:

python3 -m venv testvenv
source testvenv/bin/activate
which pip  # should be in the venv
which python  # should be as well, and in the virtualenv python=python3
pip install git+https://github.com/facebookresearch/nevergrad@master#egg=nevergrad
python mynevergrad.py

from nevergrad.

i had the exact same two issues. i can confirm that both are solved for me.

Maybe just a problem of PYTHONPATH ?
not sure, but maybe

========
pushd src/nevergrad
(or navigate to a place in which there is something at "ls nevergrad/optimization/optimizer_lib")
export PYTHONPATH=pwd:$PYTHONPATH
popd

Does it solve it ?

@salamanders can you confirm it works better now? (please close the issue if yes ;))

from nevergrad.

Thanks, I'll close this issue then, please open a new one if there is any problem ;)

git+https://github.com/facebookresearch/nevergrad@master#egg=nevergrad worked, but had the same No module named 'nevergrad.optimization' error.

The 'virtualenv' comment solved it for me, thank you!
