So I am having a bit of trouble using scipy. I have been importing data from a .mat file (matlab variables) and up until today it has worked perfectly. I have no idea what changed or when because I have been developing a text - based data format so that I can avoid depending on Matlab for writing my data. Anyways, I am getting a bizzare import error when I import scipy.io
import scipy.io
myData = scipy.io.loadmat('some_data_file')
When I run this I get the following error:
>>> import scipy.io
Traceback (most recent call last):

from ._shortest_path import shortest_path, floyd_warshall, dijkstra,\
ImportError: No module named 'scipy.sparse.csgraph._shortest_path'
I thought there might be something wrong with my python distribution so I reinstalled it, however the problem persists, and now the installer says it can't find '_shortest_path.py' when it is installing. When I navigate to .../Libs/site-packages/scipy/sparse/csgraph/ I find that indeed there is no module named _shortest_path. I don't understand how this error came about or how anything in my code would change it. Has anyone else come across this problem?
I am using Pyzo 2014 on Windows 7 x64.

I have a portable python version to use within C:\temp
I wanted to test what version of pandas is included by writing a "scrip"t that import pandas as pd and pritns the pandas version.
I usually start python via the command line which now returned an "Syntax" error in a file that I have never touched.

I am completly new when it comes to these kind of "Error messages". maybe someone can help with what is wrong here.
Pandas Core Internal block
I'm trying to run a python program that uses the pandas library on Mac OS, and I get the next error

Here's the code that I'm trying to run:
import pandas as pd
simpsons = pd.read_html('https://en.wikipedia.org/wiki/List_of_The_Simpsons_episodes_(seasons_1%E2%80%9320)')
print(len(simpsons))
print("Hola")
As you can see is not a big code and I'm getting the error, I already updated my pip3 and my python3 versions, also I reinstall pandas and I keep getting the error, if I try to import pandas in the python terminal I get the same error and I don't know what's causing it, I hope you can help me, thanks in advance.
The error message says it is a circular import error.
Try renaming /Users/adan_vazquez/Desktop/automate_python/random.py with something other than random
According to the error, it is a circular import which is causing the problem.
Since I do not have the details of your project structure or file name, my best guess is that you accidentally named your working file the same as the module name and those modules depend on each other.

Any help is appreciated!
You are using Python 3.7, but the github of requests-html states that only Python 3.6 is supported (bottom of page). I get all kinds of horrible errors when I try to use Python 3.7 but 3.6 works fine. So, seems strange I know, but please try using 3.6
Even so, as #georgexsh states, there should still be a RLock available for import from multiprocessing in 3.7 so it looks like your error may actually be that one of your code files is called multiprocessing.py or you have your own package called multiprocessing (so you are importing that instead of the module you wanted).

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

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"))
