Conflicts when installing from miniconda.

[Alex G Rice]

I am just getting started with the latest edition, but when installing from a miniconda 4.8.3 distribution, I found this was necessary (turning off strict channel priority)

echo "channel_priority: false" > ~/.condarc
conda env create -f=requirements.txt python=3.6 -n pydata-book
conda activate pydata-book
conda install ipython jupyter

Just in case anyone runs across same trouble.

Thanks, indeed it looks like the requirements.txt needs to be updated. If you or someone want to submit a pull request bumping the versions it would be a big help, otherwise I can try to fix it up in the coming weeks

Fixed this in the 3rd-edition branch: https://github.com/wesm/pydata-book/blob/3rd-edition/requirements.txt
