libgfortran.so.1: cannot open shared object file - linux

Question

I am very new to installing my own programs and packages on linux, so please be gentle ;)
I am working on Linux Mint 17.3 (Rosa) 64 bit (Ubuntu Trusty) and am trying to run through the scikitlearn tutorials located here:
https://github.com/savarin/pyconuk-introtutorial
I have installed all the relevant packages using:
pip install numpy pandas sklearn ipython
and everything looks great until I start trying to import some things from related packages i.e.
from scipy.stats import mode
I see the following error code:
sam#samputer ~/Desktop $ ipython
In [1]: from scipy.stats import mode
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)

ImportError: libgfortran.so.1: cannot open shared object file: No such file or directory
I'm also running into issues when I try to link through to R for visualisation. I add this as it may shed further light on the issue:
In [11]: %%R
....: library(ggplot2)
....:
/home/sam/anaconda2/lib/python2.7/site-packages/rpy2/robjects /functions.py:106: UserWarning: Error in library(ggplot2) : there is no package called ‘ggplot2’
res = super(Function, self).__call__(*new_args, **new_kwargs)
Error in library(ggplot2) : there is no package called ‘ggplot2’
If anyone can help me understand these issues and offer me some lines/links to fix them, I would be extremely grateful, as my googling hasn't made much progress.
Cheers!

Answer 1

If you're using Anaconda you should try installing packges with conda install first rather than pip install if you can — actually all of the the packages you installed come with the standard Anaconda distribution, so I would try reinstalling this first (did you install miniconda?)
For your second question I'm guessing you'll need to install ggplot in R, I think you do this by running install.packages("ggplot2") in R.
