Cant install using conda on linux

[amcpherson]

From the instructions:

conda create -n ete3 python=3

installs the latest version of python 3, which doesnt work with ete3, the subsequent conda install ete3... step fails. I had to modify to:

conda create -n ete3 python=3.6

to get the ete3 install step to succeed.

Once ete3 is installed, if i do:

python -c "from ete3 import Tree"

I get the following output:

Traceback (most recent call last):
  File "/home/mcphera1/miniconda/envs/pdac_dlp/lib/python3.6/site-packages/ete3/clustering/clustvalidation.py", line 196, in <module>
    from scipy import stats
ModuleNotFoundError: No module named 'scipy'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<string>", line 1, in <module>

    geometricmean = Dispatch ( (lgeometricmean, (ListType, TupleType)), )
NameError: name 'ListType' is not defined

which can be solved by installing scipy:

conda install scipy

However, now if i try to render a tree, ie:

python -c "from ete3 import Tree
t = Tree('((a,b),c);')
t.render('test.png')"

I get the following:

Traceback (most recent call last):

pyqt5 is installed, but not pyqt4. Not sure where to get pyqt4.
