I tried installing pandas using easy_install and it claimed that it successfully installed the pandas package in my Python Directory.
I switch to IDLE and try import pandas and it throws me the following error -
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
import pandas
File "C:\Python27\lib\site-packages\pandas-0.12.0-py2.7-win32.egg\pandas\__init__.py", line 6, in <module>
from . import hashtable, tslib, lib
File "numpy.pxd", line 157, in init pandas.hashtable (pandas\hashtable.c:20282)
ValueError: numpy.dtype has the wrong size, try recompiling
Please help me diagnose the error.
FYI: I have already installed the numpy package
Maybe you interrupted pandas install , retry using pip :
First install pip (if you haven't done it already) :
easy_install pip
then reinstall pandas:
pip install pandas --upgrade
Hope it helps
You know that output error you got when you tried running #nipun-batra's script?
Well, you got it because you have to first:
import platform
before you can run:
platform.platform()
I know this because I--about 10 minutes ago--got the same error when trying to run the same script. The difference is that I--an absolute beginner--figured out our problem after a quick trip over to google. (Man, they let you search for anything over there!)
This, when coupled with your follow-up appeal exactly two months after your initial posting, suggests to me that you would prefer to minimize--as much as possible--the usual hardship associated with owning and operating your own computer-machine-thingy.
As a result, with respect to your initial IDLE/pandas issue, your best best bet is to forget about messing around with easy_install, etc. Instead, go head on down to Continuum Analytics and pick up your very own (free) copy of Anaconda, which has got more packages than you can shake a stick at! (Including, I might add, pandas, numpy, scipy, statsmodels, matplotlib, IPython, and many more). And the best part is that it all comes bundled together as a single easy-to-download file. Trust me, it will save you a lot of headaches if you just download everything all at once.
Hope this helps!
Panda does not work with python 2.7 , do you will need python 3.6 or higer

I tried to download Graphlab from Turi wit the following tutorial. I coded with their tools and tried to compute a Python script but it answered me an ImportError.

Actually it cames often on the server when I tried to download with pip numpy, scipy, sklearn... Like we can see in the following conversation (in Spanish) between FJSevilla and the man of my team I'm working with.
Two things: (1) check the version of your Python console and see if it matches or is higher than the compatibility with the packages. If you look at the depreciation message and read it through, you would understand what is going on a little more. (2) be careful of what you are importing and how you import them because your formatting might also be a syntactic all error. One thing you could do is find the package, manually download, unzip, then run the setup.py.
I apologies for the trivial question but when I tried to run a few scripts this morning that had been working for months I came across the following error message:
import scipy.stats
Traceback (most recent call last):
File "<ipython-input-5-b66176eb2d0a>", line 1, in <module>
import scipy.stats
ImportError: No module named stats
So I get the problem that Python doesn't seem to find the stats package in the scipy folder, yet I double checked that I indeed had a scipy folder in the Python install directory as well as a stats folder within the scipy folder.
I do have the following: C:\Python27\Lib\site-packages\scipy\stats\
I use Spyder, I tried reloading the kernel, closing and reopening Spyder but nothing seems to work.
Further info;
I do have an __init__.py in the scipy folder.
The import scipy command works
attempts to load other packages within scipy also throw the error
Any help would be very welcome if you encountered the same problem before !
EDIT:
Okay so I restarted the kernel from the python console once more and did the following, which works:
import os
os.getcwd()
Out[2]: 'C:\\Python27\\lib\\site-packages'
from scipy import stats
The bug has now moved on to another package...
I suspect that when I am running my script which is located on another drive Python struggles to find the packages. My puzzles me is that it didn't use to.
I have been experiencing the following problem with pandas for days: I can import pandas when I use spyder but it does not work when I use ipython or jupyter. I have been looking in several directions to solve the problem:
I have updated pandas,
I have checked that ipython and spyder have the same pythonpath,
I have uninstalled and reinstalled spyder
It still does not work and I get the following error message:
ImportError Traceback (most recent call last)
<ipython-input-8-d6ac987968b6> in <module>()
----> 1 import pandas
/Users/ME/anaconda/lib/python2.7/site-packages/pandas/__init__.py in <module>()

30 "'python setup.py build_ext --inplace' to build the C "

33 from datetime import datetime
ImportError: C extension: hashtable not built.
If you want to import pandas from the source directory, you may need to run
'python setup.py build_ext --inplace' to build the C extensions first.
I see that other people had the same problem but there is no clear answer. Does anyone know the procedure to solve it ?
I found the solution: the error comes from a value error due to an encoding problem.
It happens quite a lot in python and various questions have been asked about it. Among them, the following link explains it carefully:
Pelican 3.3 pelican-quickstart error "ValueError: unknown locale: UTF-8"
To be short, one only needs to run the following bash code to solve the problem:
echo -e "export LC_ALL=en_US.UTF-8\nexport LANG=en_US.UTF-8" >> ~/.bashrc && source ~/.bashrc
OS: CentOS 6.6

So, I've (re)installed Canopy after it suddenly stopped working after an abrupt shutdown. It worked fine immediately after the install (I installed as my default Python). But after one reboot, when I try to open it with /root/Canopy/canopy (the icon under applications no longer works, either), I get the following error:
(Canopy 64bit) [xxuser#xxlinux ~]$ /root/Canopy/canopy Traceback (most recent call last): File "/home/xxuser/qiime_software/sphinx-1.0.4-release/lib/python2.7/site-packages/site.py", line 73, in <module>
__boot() File "/home/xxuser/qiime_software/sphinx-1.0.4-release/lib/python2.7/site-packages/site.py", line 2, in __boot
import sys, imp, os, os.path ImportError: No module named path
I found this link: Python - os.path doesn't exist: AttributeError: 'module' object has no attribute 'path', but both of my os.py and os.pyc were 250 and 700 bytes, respectively. There was another file called site.py which was 0 bytes and site.pyc was about 100 bytes. What are these files? And would deleting them hurt anything (which is what they did)? And why is this happening after reboot? (using reboot command).
I also found this: https://groups.google.com/forum/#!topic/spyderlib/hKB15JYyLqM , which could be relevant. I've updated my python path before with sys.path.append('/..')
My guess is that for some reason os.path isn't in sys.path? and __boot can't find it? But I'm new to Python and Linux and want to know what I'm doing before I go modifying any boot files, paths, etc.
Thanks in advance.
More information (saw that I'm supposed to update new info in an edit to original question. New to this.)
From one of the comments:
This is what I got:
import os.path
import posixpath
os.path
module 'posixpath' from '/home/xxuser/qiime_software/python-2.7.3-release/lib/python2.7/posixpath.pyc'
posixpath
module 'posixpath' from '/home/xxuser/qiime_software/python-2.7.3-release/lib/python2.7/posixpath.pyc'
Looks like os.path is there.
Could this have to do with a permissions error? I have it installed to /root/Canopy/canopy and I found this: docs.python.org/2/library/os.html#module-os (section 15.1.4). Does that make sense?
I'm also not sure if the following is related, but it might possibly. I can no longer seem to update my path with sys.path.append('/file/path/here'). It works until I close the terminal, then I have to re-append the next time I want to call a module from the new directory. Are sys.path and os.path related in any way?
Just fixed this on OSX with:
brew uninstall python
brew install python
No idea why, never seen it in 5 years of working with Python :S
It turns out that I was onto something with my last comment.
I'd downloaded a bunch of biology modules that depend on python, and so many of them came with their own install. When I added the modules to ~/.bashrc, my bash began calling them in advance of my original CentOS install. Resetting ~/.bashrc and restarting (for some reason source ~/.bashrc didn't work) eliminated all of the extra stuff I'd added to my $PATH and Canopy began working again. I'm going to go through and remove the extra installations of python and hopefully the issue will be behind me. Thanks to everyone who posted answers, especially A.J., because that's what got me thinking about .bashrc .
Edit: With some better understanding, this was all because of using python in a virtual environment. Canopy was resetting my path every time I opened it. I'm using a self-installed virtual environment now and have configured my path.
Try seeing if you have posixpath by typing import posixpath:
>>> import os.path
>>> os.path
<module 'posixpath' from '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/posixpath.pyc'>
>>> ^D
bash-3.2$ python
>>> import posixpath
>>> posixpath
<module 'posixpath' from '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/posixpath.pyc'>
>>>
I tried looking for an answer to this around the forum/google, but I can't find anything. My issue is this (from python console):
>>> import pandas
cannot import name hashtable
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python27\lib\site-packages\pandas\__init__.py", line 6, in <module>

ImportError: cannot import name hashtable //also can't import name NaT somtimes
I ran the windows 1-click installer prior to attempting the import. I'm running everything 32-bit. The pandas installer is for python 2.7.
Here's a list of modules that I have correctly imported into Python.
setuptools
pip
mox
dateutil
six
numpy
SQLAlchemy
I'm on windows 7.
I also have anaconda installed, but that was really just a "hail mary" after I tried everything else. My end goal is to install the ultra-finance module. However, it seems to require pandas, hence me being stuck.
I'm a python noob, so please don't assume I know anything. Thanks.
EDIT: please let me know if I can provide any extra information.
The recommended way to install pandas is via pip:
pip install pandas
This hashtables error arises from the cython files not being built. This error message will be more informative from 0.11.1.
Try running your code in Spyder (Anaconda -> Spyder). It worked for me.
Check that you have python scripts included in your system path variable. In my case I had to add "C:\Python27\Scripts"
I was having a similar problem when downloading Pandas to my Windows 8 system. The first error I had was an egg error, but after installing some packages I think I have the solution.
First look at the previous pip errors with Pandas, make sure you have the most updated pip.
The second part is downloading wheel using
pip install wheel
After installing wheel and having the dependencies for panda and using pip it worked correctly.
