Problem trying to install Naoqi Python-SDK: "SystemError: dynamic module not initialized properly"

I saw someone was answering the same question here: Python for Naoqi (dynamic module not initialized properly), but I follow the answers in the page, still cannot get it working. Could someone advice how to proceed?
Using Python 2.7.10 doesn't help.

I found out the problem. The system Python 2.7.10 came with the Mac OS X doesn't work. I have to download the Python 2.7.10 from the Python website and install that in order to have it work: Python Release Website

Cycling between "No module named functools_lru_cache" and "cannot import name cbook" errors

I am completely new to Python but I enjoyed it very much. I start with Python 2.7 before migrating to Python 3 since many applications for work have to do with Python 2.7.
I have quite sadly many version of python2.7 on my MacBook. One from Apple, one from Homebrew, one from Anaconda. I have pip version 18.0 installed.
I wanted to install many modules (scipy in particular) and I ran into the following problem.
On the console:
Python 2.7.15 (v2.7.15:ca079a3ea3, Apr 29 2018, 20:59:26)

>>> import matplotlib
I get the error message:

from backports.functools_lru_cache import lru_cache
ImportError: No module named functools_lru_cache
I looked on the web and found the solution for that by typing:
pip install --user matplotlib
Now when I do:
>>> import matplotlib
I get the message:
Traceback (most recent call last):
File "", line 1, in
import matplotlib
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/init.py", line 126, in
from . import cbook
ImportError: cannot import name cbook
There is a confusion on the web about how to solve this problem. Is there still hope I can get back running?

error with snappy while importing fastparquet in python

I have installed installed the following modules in my EC2 server which already has python (3.6) & anaconda installed :
snappy
pyarrow
s3fs
fastparquet
except fastparquet everything else works on importing. When I try to import fastparquet it throws the following error :

How do I go about fixing this ?

Unfortunately, there are multiple things in python-land called "snappy". I believe you may have the wrong one, in which case one of the following conda commands should solve this for you:
conda install python-snappy
or
conda install python-snappy -c conda-forge
where the latter is slightly more recent (releases the GIL which can be important in threaded applications).

Cannot import python naoqi library after upgrading Ubuntu 14.04 to 16.04

I have recently upgraded the system to 16.04 Gnome. The most troubling thing that I am facing is that I cannot import a NAOqi library for my work. The python version of this library was pretty simple to set-up. One just has to untar the file and then enter a path variable called PYTHONPATH pointing to this library and it worked like a charm in 14.04. Now since upgrade I am facing:

If I add a path variable:

The error changes to:

Please help me what should I do to get it working? I have also used python 2.6.9 but same error occurs with error below.
ImportError: libboost_python.so.1.55.0: cannot open shared object file: No such file or directory

Installing libboost1.55 did the trick. 16.04 comes with libboost1.58 but naoqi is not yet compatible with it. Manual installation of libboost1.55 solved the import error.

Python Error: IPython.display import Markdown as display

I am trying to use the pydna module on a machine running Ubuntu 14.04, and am getting the following error when I try to import it:
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/pydna/__init__.py", line 97, in <module>
from pydna.amplify import Anneal
File "/usr/local/lib/python2.7/dist-packages/pydna/amplify.py", line 32, in <module>
from pydna.dsdna import rc
File "/usr/local/lib/python2.7/dist-packages/pydna/dsdna.py", line 63, in <module>
from IPython.display import Markdown as display
ImportError: cannot import name Markdown
Has anyone found a way to resolve this? I have tried reinstalling IPython, and pydna. The offending chunk in dsdna.py is the following:
(lines 58-63)
try:
import IPython
except ImportError:
def display(item): return item
else:
from IPython.display import Markdown as display
Any help would be greatly appreciated!
(Python 2.7.6)

I have the IPython 4.1.1 installed and it works for me (see below). Which version do you have? Also, which pydna version did you install?
This could be due to a too old version of IPython, recently IPython was split into IPython and Jupyter which caused some code to break.
