Error on import when using Python 3

See original GitHub issue

I installed plotnine in Python 3 using the command pip install plotnine.

Running python -c "from plotnine import ggplot" yields the error

It installs and loads fine from a Python 2 environment.

As far as I can tell, scipy 0.18.1 is not the problem. It may have been a case of mixed up packages.

This works for me:

# In a new virtual environment
$ pip install scipy==0.18.1
$ pip install plotnine
$ python -c "from plotnine import ggplot"

Even checking the scipy code, the logistic function is present in v0.18.1 and in much older versions.

I did not set a minimum version of scipy because it has not always been easy to install on all platforms. v1.0.0 may have changed that but I am not sure if that will always be the case.

It is not necessary to chase down the root cause, unless you run into it again. Leave the PR open, I’ll look more into the availability of v1.0.0.
