I've encountered a very strange error when trying to Import mayavi. A few minutes ago it worked like a charm, but now there's something going wrong and I've no clue why.
I start python from the terminal and then I type:
from mayavi import mlab
The error I get:

What's wrong with Python?
You have a local file named pickle.py; this is being imported instead of the pickle module. This module then tries to import mlab before that module itself has completed importing in a circular import dependency:
File "/usr/lib/python2.7/subprocess.py", line 432, in <module>
import pickle
File "pickle.py", line 4, in <module>
from mayavi import mlab
Note how subprocess tries to import pickle and finds your file instead (the path is relative instead of a full path inside /usr/lib/python2.7/.
Rename pickle.py to something else, you are masking the standard library here.

What does this error code mean? (see first answer for error code) I got this while attempting to open a csv file and read the first 5 rows of data.

This is the python 3 code i attempted to run:
import numpy as npy
import pandas as pd
data= pd.read_csv("cti-april02-log")
data.head()
you have a file named random.py that override the module with the same name from the standard library (i.e. it try to import random from your file random.py, not the module in the standard library
I'm using Python 3.6 in Ubuntu 16.04.
From this very simple program:
import pandas_datareader.data as web
import datetime
amzn = web.DataReader("AMZN", "yahoo", datetime(2000,1,1), datetime(2015,1,1))
I get this very impressive error list:

I've really now idea what is causing this error other than it's occurring when the program tries to import pandas_datareader.
I am new to the data_reader but I'm pretty sure the import command is syntactically correct.
Can anyone suggest what the problem is?
I think you have shadowed Python module argparse with your own /SAT/argparse.py.
/anaconda/lib/python3.6/unittest/main.py in line 4 tries to import argparse (the standard Python module), but your module (which has an error len(sys.argv) > 1:) jumps in first.
Try to rename /SAT/argparse.py to /SAT/my_argparse.py
PS try to name your own scripts and directories differently so that they don't shadow stardard Python modules
Try this:
import datetime
import pandas_datareader.data as web
amzn = web.DataReader("AMZN", "yahoo", datetime.datetime(2000,1,1), datetime.datetime(2015,1,1))
My code is simply the follow and work few days ago:
import pandas as pd
df = pd.read_csv('WORLDBANK-ZAF_MYS_PROP_4044_SEC_MF.csv')
print(df.head())
But now whenever I try to run it by calling python my_io.py on my Mac terminal it generates the following messages:

Can someone please help me, I have no idea what is going on here..
Your file is called io.py, which is a library module to handle file-like buffers among other things.
pandas imports tempfile which needs it:
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/tempfile.py", line 32, in <module>
import io as _io
and your filename gets in the way of the import chain and prevents import from going through.
Just rename your file with something more specific (like my_io.py for instance?)
I have been trying to import theano.tensor in my code.
I have used theano.tensor before. All of my previous code importing theano.tensor works perfectly in my machine. Now I am trying to write another script importing the tensor from theano and I am getting the following exception.

I cannot find any plausible reason for this exception.
I guess i got your problem. See in the error log:
File "/anaconda3/lib/python3.5/pdb.py", line 75, in <module>
import code
I believe there is another script called code.py in Theano which gets called from pdb.py when python interpreter executes your script which is also named as code.py. I am guessing python interpreter is mixing up these two scripts and executing the wrong one! You can change the filename and check whether the error disappear or not.
I used py2exe to build an exe of a program that uses scipy and numpy and I get the next error in the log file when I tried to run the program.

I have tried some thing like put my setup.py file like this:
options ={
'py2exe': {
'bundle_files' : 3,
r'includes':[r'scipy.sparse.csgraph._validation',
r'scipy.special._ufuncs_cxx',],
'packages' : ['encodings'],
}
},
But it doesn't work and I still get that error.
I don't know what to do to solve this issue...
Hope you can help me.
Thanks.
I have been solve the issue adding in the "includes" section of my setup.py all the files that the log file return me as missing. After 7 files, the program run without any error.
