pip install - can't import, like issue #89

[sjspielman]

Hi,

I am receiving Import Errors with a fresh install of ete3 from pip (11/27/2017), such that many ete3 modules cannot be loaded. It seems similar to the long-closed issue #89. Perhaps this is related to a pip update I see happened on 11/3?

For example, see:

Stephanies-MacBook-Pro:~ sjspielman$ sudo pip install ete3
Collecting ete3
Installing collected packages: ete3
Successfully installed ete3-3.1.1
Stephanies-MacBook-Pro:~ sjspielman$ python try_ete.py 
Traceback (most recent call last):
  File "try_ete.py", line 1, in <module>
    from ete3 import Tree, faces, AttrFace, TreeStyle, NodeStyle
ImportError: cannot import name faces

In above, only Tree can be imported, rest throw the error when I have tried on their own.

Thanks in advance!

most probably you are missing qt/pyqt. Can you do from PyQt5 import QtGui? (or PyQt4...)

[sjspielman]

I see, thanks. I have installed PyQt5 and it works now! I wasn't able to get this working yesterday because I didn't realize that PtQt5 was python3-compatible only, and hence cannot be retrieved with pip, just pip3. Perhaps this is common knowledge, but if not, may be useful for know for any ete users in python2. Indeed, I had this issue because I installed ete3 w/ pip, which simply bailed on getting the PyQt dependency due to versioning.

Thanks again!
