I was trying to get this ConvexHull function running, and I needed numpy (I think) to get it to work. I'm going to try to get numpy uninstalled and reinstalled, but I'm not sure why/how this happened so that I can prevent it from happening again.
While I was running through some of the examples, I decided to stop running from the prompt to save some typing. When I ran the seemingly same bits of code from a file, it returned the following error message:
>>>
Traceback (most recent call last):
File "<frozen importlib._bootstrap>", line 2218, in _find_and_load_unlocked
AttributeError: 'module' object has no attribute '__path__'
During handling of the above exception, another exception occurred:

Now, when I type import numpy from the prompt, it returns:

The entire setup was running without issue a few minutes ago, and I am unsure exactly why this all stopped.
The full text of my commands is here. The file was short, C:\Python34\numpy.py with the following contents:
from scipy.spatial import ConvexHull
import numpy as np
points = np.random.rand(30,2)
Change the file name to something different than numpy.py.

I have a folder structure like so
root/
A0/
A1/
B0/
B1/
Lets say I have a file called test.py. In it, I import numpy like so
import numpy as np
That is all that is contained in the file. This works without issue when it is located in root, subfolder A0,A1,B0 but raises an error in subfolder B1. Is error raised is as follows:

Importing as modules (e.g cv2) also leads to errors, but only wrt to numpy:
ImportError: numpy.core.multiarray failed to import
Traceback (most recent call last):

ImportError: numpy.core.multiarray failed to import
What may be the cause of such an error?
If your start script is located in .../pose/utils then every absolute import looks for modules there, too. This directory contains a module named logging (like the one in the standard library).
During the initialization of the numpy package (executing its __init__.py) and before numpy.testing is available the usual chain of imports happens (as can be seen in the traceback) which leads to the wrong logging module which in turn leads to import of _numpy_compat which tries to access numpy.testing too early.
To avoid this circular import problem you can either rename your logging module or move the start script to another directory.
I have recently properly installed numpy and scipy. The following line runs without error.
import scipy
I am experiencing difficulty using scipy.io.wavefile. I have been trying to use the code from the "best answer" of this post.
However, when I try the first line,

I do not understand why the module can not be found, if scipy is properly installed and can be imported by itself. I am using python 3.7.1. Could the code from the post be depreciated?
Apologies in advance for the long post.
Both error messages are complaining about the scipy.special._ufuncs module and a quick search revealed a few other posts, like this one, that suggest making sure you have the Visual C++ Redistributable Packages installed: https://www.microsoft.com/en-us/download/details.aspx?id=48145
I'm having a big problem with the testing framework in IntelliJ using with the python plugin.
When I launch my tests, written using unittest, the tests fail with an import error in the _jb_test_runner file.
I surfed the net for a while, but didn't get a useful solution. See the stacktrace below:

The code does not present any syntax error, but the problem started after a refactoring of the whole project I'm working on.
Thanks in advance.

IndentationError: expected an indented block
I executed this command in a terminal (ubuntu 16.04 LTS system). I did not find anything about this error and the indentation doesn't look wrong.
The SyntaxError is in your file new.py (I guess it's in your current working directory). Try to switch to a directory where no new.py file is present (or move the new.py file in another directory), then the internal scipy import should work without problems.
On the other hand you can just upgrade to scipy 0.19.x. They removed the import there and it should work without problems.
Note that it's always a bad idea to name python files like builtin-modules! That's a common source for exceptions or unexpected behaviour.
everyone,I am new to PP but got stuck in a problem when importing NumPy with PP.
Basically what I tried to do was submitting a function to the ppserver which depends on NumPy. I have imported it at the very beginning of the code using (import NumPy as nu) but when I ran the code, it gave me the error that cannot find the shared object multiarray.so.
The situation is exactly the same here: parallel python forum
the code is attached as below: (I am running on python 2.7.2 + pp 1.6.0 + numpy 1.5.1)
import numpy as nu
import pylab as pl
import pp
job_server = pp.Server(secret="123456")
print "Starting pp with", job_server.get_ncpus(), "workers"
aa = GrRib()
job = job_server.submit(aa.plotwavefunc, (band,k),(nu,pl,signal))
result = job()
the error looks like :
An error has occured during the function import
Traceback (most recent call last):

Can anyone help me out? I understand it as I will have to change the directory PP is looking for pyshared objects.
I could be wrong, but I believe the way you submit the job is wrong. As seen on the documentation (http://www.parallelpython.com/content/view/15/30/#QUICKSMP), the third argument (not including "self") are dependent functions. Also, the modules have to be strings. I'm assuming the "band" and "k" are dependent functions since I do not see their declarations:
job = job_server.submit(aa.plotwavefunc, depfuncs = (band,k), modules = ("numpy","pylab","signal"))
