cannot import name ExtendedInterpolation - python

Interestingly, on my machine (OSX) importing the package hgvs runs smoothly, even though I'm working on python 2.7 (and ExtendedInterpolation is a python 3 function from configparser). As far as what I've gathered, it simply uses a backport of Python 3's configparser module, so it should work anyways if Python 3 is installed.
However, the following error occurs when I try to import the module on a EC2 instace using iPython Notebook.
Any ideas of what may be causing the issue?

According to this the problem is that:
Unfortunately in 0.14.0 they broke the configparser import by introducing their own.
To resolve it, I downgraded the future library:
pip install future==0.13.1

Importing wordcloud using Jupyter Notebook (Python)

I am using jupyter Notebook(conda root). The python version I am running is 2.7
I am having a hard time getting wordcloud installed into my environment. Here's the code

You have problem with part of python Pillow module: with a library, that builds from _imaging.c. Try to reinstall python Pillow module from .exe package, not with pip.

ImportError: No module named request when importing BeakerX into Jupyter

I am trying to import beakerx into my jupyter environment like so:
from beakerx import *
However, I get the following error:

I am not sure what this error means? Also, it seems to be looking into python2.7 directories even though this is a python 3 script? I installed beakerx using: pip3 install beakerx and can see the files in the right folder within the right folder:
anaconda3/pkgs/beakerx-0.12.2-py36_2/lib/python3.6/site-packages/beakerx
This seems to be how every other module is stored but I cannot get it working for some reason. Can anyone help?

Datashader has snappy error

I was using python's datashader 0.5.0 package to plot population density information, generally following the tutorial https://www.continuum.io/blog/developer-blog/analyzing-and-visualizing-big-data-interactively-your-laptop-datashading-2010-us . I installed datashader using conda install -c bokeh datashader=0.5.0.
All was fine. Though perhaps unrelated, things seemed to break as soon as I installed the haloviews and geoviews packages. After installing these additional packages, I can no longer import datashader and my once working code no longer runs. When importing datashader, I get the following error:
AttributeError: module 'snappy' has no attribute 'compress'
I am running on windows 10, anaconda python 3.5.3.
Perhaps I'm going down the wrong rabbit hole, but I thought perhaps it was the snappy package. I ran "conda install -c conda-forge snappy=1.1.4". conda list reveals that snappy is installed. Snappy does import. The snappy.compress object is not found. My issue seems related to the following SO post as I also had a fastparquet error when trying geoviews: error with snappy while importing fastparquet in python
When running import snappy, print(snappy.__filename__) gives the following error:
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-5-b8565733b383> in <module>()
----> 1 import snappy; print(snappy.__file__)
AttributeError: module 'snappy' has no attribute '__file__'
I also tried uninstalling through both conda and pip just in case. Still no joy.
Running "pip install python-snappy" results in a "failed building wheel for python-snappy" error preceded with " error: Microsoft Visual C++ 14.0 is required..." So I went and got the "Microsoft Visual C++ Redistributable for Visual Studio 2017" and ran it, but had no change.
Any thoughts on how to resolve this? For reference, the full error on datashader import is as follows:

It turns out that in adding packages, something messed up the snappy install. I followed this solution: How to install snappy C libraries on Windows 10 for use with python-snappy in Anaconda?
It was a snappy error, not a datashader issue, but I'll leave the post in case anyone has the same series of issues.

Python can't import tika

I am having trouble importing tika in a python file. I have spent a lot of time googling and been unable to find anything. Here is the iPython command: import tika, and subsequent stack trace.
It occurs to me that there could be a problem with a module on which tika is dependent, such as requests, or urllib3. However, when I try to install those with pip, it says requirement already satisfied. I have also double checked the PYTHONHOME director, and I'm 99% sure it's correct.

ValueError: source code string cannot contain null bytes
In case anyone else is looking at this, here is how I finally solved my issue.
I had been mistakenly assuming that the python-tika module was a fully packaged, ready to run version of tika. In fact, you need to download the java tika server from Apache, and it must be running when you use python-tika (you can easily just run the server on localhost).
The Python-tika module then allows you to make requests to this server from your python code. I probably should have known this but for some reason I didn't pick it up in the documentation.
Are you sure you have that module installed?
If not, just go to the Command Prompt and type pip install tika
I think here is a good approach for installing tika on the Windows:
First, install java SE from this link:
https://www.oracle.com/ca-en/java/technologies/javase-downloads.html
Second, install a specific version of tika:
pip install tika==1.23
Third, download and run the tika server and tika app files from apache:
https://archive.apache.org/dist/tika/tika-server-1.23.jar
https://archive.apache.org/dist/tika/tika-app-1.23.jar
it should be fine, and you should be able to run tika in your application.

Jupyter (IPython) notebook numpy/pandas/matplotlib error (FreeBSD)

I am trying to set up a Jupyter notebook server at home. It has taken me a long time, but I have build and installed Python 3.4 and all the required packages from FreeBSD ports successfully. The notebook server is up and running fine, except every time when I try to import numpy:
In[1]: import numpy

ImportError: /lib/libgcc_s.so.1: version GCC_4.6.0 required by /usr/local/lib/gcc48/libgfortran.so.3 not found
The error messages for importing pandas and matplotlib are different, but I suspect that has something to do with this numpy import error.
Strangely, all 3 packages work fine in Python and IPython consoles with no problems at all!
I have googled and made the following attempts:
delete and reinstall numpy -> no change
append numpy directory to sys.path -> no change
install a lot of other external packages just to see if it's only related to numpy -> they are all working fine in both consoles and notebook, except scipy giving some error related to numpy
Thank you for your help!
My gcc is version 4.2.1.
I have fixed this by setting the LD_LBRARY_PATH to /usr/local/lib/gcc48. gcc48 is already installed in my system.
To avoid setting the path every time, I've added the following line to /.cshrc:
setenv LD_LIBRARY_PATH /usr/local/lib/gcc48
edit:
This won't work is you want to start the notebook server automatically by adding to crontab:
#reboot /usr/local/bin/jupyter-notebook
the same error appears when trying to import numpy and modules depending on numpy
I fixed this by making a copy of /usr/local/bin/jupyter-notebook and added the following lines:
import sys
import re
----------------- add these 2 lines below --------------
import os
os.environ['LD_LIBRARY_PATH'] = '/usr/local/lib/gcc48'
....
Add the new file to crontab instead of jupyter-notebook.
The issue is not with your python modules. The error message at the bottom, where it says ImportError: /lib/libgcc_s.so.1: version GCC_4.6.0 required by /usr/local/lib/gcc48/libgfortran.so.3 not found indicates that it's a dependency error with the Fortran library. Apparently it wants gcc 4.6 or higher, and apparently you have a lower version installed. Not being familiar with Python libraries or your setup, my guess is that it could be an issue with /usr/ports/devel/py-fortran. I would recommend checking the gcc version on your machine with gcc -v and whatever fortran-related ports you have installed with pkg info and then take it from there.
