I just added subinterpreter to my c++ embedded python editor to have a clean interpreter for each execution.
PyThreadState* tmpstate = Py_NewInterpreter();
PyThreadState_Swap(tmpstate);
... run the script ...
Py_EndInterpreter(tmpstate);
My own module are working and I tested numpy without having any problem. The problem is with matplotlib
if I run that the first time everything looks fine. The second time i get :

This seem to be a bug in Python 3.3 : http://bugs.python.org/issue17408
The problem is :
The reason is in Objects/typeobject.c: import_copyreg() has a static cache of the copyreg module.
When the interpreter stops, the module is filled with None... but gets reused in the next instance.
Resetting this "mod_copyreg" variable to NULL fixes the issue.
pickle is also broken for the same reason.

I am very new to tensorflow, struggling on its installation. I use ubuntu 16.04. I obviously installed the Nvidia dependencies.
Whenever I type in:

I tried many solutions, but the effect remains the same. Many thanks for help!
I had this same problem when installing gputools in R. After hundreds of tries, the command which worked for me is:
sudo ln -s /usr/local/cuda/lib64/libcublas.so.8.0 /usr/lib/libcublas.so.8.0
OR
sudo ln -s /usr/local/cuda-8.0/lib64/libcublas.so.8.0 /usr/lib/libcublas.so.8.0
I am a beginner in programming, started from Python. I learn by Dr Charles Severance materials. So in his book there is an example:
import urllib
fhand = urllib.urlopen('http://www.py4inf.com/code/rom...
for line in fhand:
print line.strip()
When I copy paste it to Python 2 version (I use PyCharm 5.0.4) there appears:
Traceback (most recent call last):

When I type another example, gets an error also. What is wrong? I don`t even write a program. I just copy paste an example. Asked Dr Chuck - still no answer.
Try this:
import urllib
fhand = urllib.urlopen('http://www.py4inf.com')
for line in fhand:
print line.strip() # notice the indentation
So I without thinking stupidly named a file io.py in my working directory. When I tried to compile I got a traceback error. Having realised what I'd done I renamed my file and updated references to it but I still get the following error:

I have restarted PyDev to no avail. I have refreshed the interpreter to no avail.
I have followed the instructions found in this Python issue but that command returns the correct result on my machine.
Is tempfile.py a temporary file I can remove to resolve this issue?
I have found the solution. Stupidly simple but maybe worth leaving here for other newbies who fall into the same trap.
PyDev compiles the code into *.pyc files. When you update the references and rename the files these aren't immediately recompiled. Deleting the io.pyc file I had allowed compilation too run properly.
I found some more info on common pitfalls too.

Include sklearn.utils.lgamma in your py2exe setup file.

I had a look at shapely and it seems like you are using an outdated version.
Update your current install:
pip install -U shapely
