The enthought site says pandas is included but I've installed on both windows and Linux and doing a 'import pandas' gives a "ImportError: No module named pandas found". Is pandas included with EPD Free 7.3?
Update :
Ok think I was slightly misled by the EPD Free download page which says that EPD includes pandas but if you go to the detailed list of libraries pandas is not included
EPD Free 7.3 installer did not ship with Pandas, and hence the import error. But, if you have a registered EPD Free account, you can use enpkg to install pandas. Look at this support page for more info.

I'm trying to do an
import sparknlp
on the Databricks platform and I'm getting a similar message to the one reported at After installing sparknlp, cannot import sparknlp
I can't figure out how to get the python wrapper installed... I can access the spark-nlp library via Scala but I can't get the python version working. Any tips would be greatly appreciated!
These error can be produced due to sparknlp jars have been loaded correctly, but python wrappers library can not be imported. Make sure you have installed those wrappers correctly. Check out the sparknlp documentation site
As is said in documentation webpage, make sure that after install python sparknlp library:
pip install --index-url https://test.pypi.org/simple/ spark-nlp==1.5.4
that your environment variable PYTHONPATH can locate sparknlp wrappers.
I just installed Canopy Express 1.4.1 (32-bit) for Windows. Among the packages that are supposed to be there (see https://www.enthought.com/products/canopy/package-index/ ) are pandas and statsmodels. But after installing, neither is listed in Package Manager, either as being installed or available.
The lack of pandas is not a problem, as pip easily installs it. (Enthought notes that packages installed that way will not be listed in Package Manager, but are fully available in the Canopy User Environment. Indeed, it imports.
statsmodels is not so easy. pip only gets source, and there is no Windows installer provided by the statsmodels folks. There is a nightly Windows binary, but not (if I'm reading correctly) for the stable build. The suggested solution by statsmodels is to compile it, using MinGW, which I do not currently have installed.
With enough trouble, I imagine I could compile and install, but is there a way to save all that trouble and get the packages within Canopy, as Enthought says it should be?
Seems like your Package Manager is misbehaving or you are looking in the wrong place (look in Free Packages not Community Packages).
Pandas is indeed in the Express installer, so always installed. At Canopy's python prompt, type:
import pandas
Though sounds like you've already overwritten it with pip, not really a problem but not the cleanest path (mixing 2 different installation methods for the same package).
Statsmodels is listed in package manager (Free package). It is available to free users but is not yet in the Express installer.
If you still don't see these in the pkg mgr, please quit Canopy, ensure that all Canopy processes have terminated (easiest way... log out of Windows, then back in), and restart Canopy.
import wx.lib.activex fails with the supplied version of wx in Enthought Canopy or EPD on Windows. How can I get the activex container to work with the Enthought Python Distributions?
First of all, it's necessary to install comtypes, which is a dependency not available through the Enthought package manager.
The more serious problem however, is that Enthought seem to have erroneously omitted the two myole4ax.* files which are necessary to use the activex container in wx Python. You can copy these files by downloading the wxPython-src tarball from the project page, and copying the two myole4ax.* files (e.g. from wxPython-src-2.8.12.1\wxPython\wx\lib) to the %python root%\Lib\site-packages\wx\lib folder.
I want to install Go on CentOS 5.x, but Go website here http://golang.org/doc/install mentions that it is not supported.
Is there still some way to install Go Language on CentOS since CentOS is just a different flavour of Linux?
When I installed the same and ran the sample program hello.go mentioned at above website
I got the error
hello.go:3:8: import "fmt": cannot find package
package runtime: import "runtime": cannot find package
% export GOROOT=~/
% go run test.go
test.go:3:8: import "fmt": cannot find package
package runtime: import "runtime": cannot find package
Not finding the "runtime" package tells you that the $GOROOT enviroment variable isn't set to golang root directory.
You need to set $GOROOT. Also you should set the $GOPATH variable if you use external packages (go help gopath for more information).
A typical setup (not specific to CentOS) would be:
export GOROOT="/usr/local/go"
export PATH="$GOROOT/bin:$PATH"
export GOPATH=/Users/rodowi/gocode
At least for some programs it works fine. I have a production program that I compile on RHEL 6.x and deploy on 5.x and 6.x and it is working without any problems.
Edit: I used to use it under 1.0.3, but a few months ago I upgraded to "tip go" (the soon to be 1.1 version). Under 1.x it'd crash on 5.9 when accepting a tcp connection but that was fixed a few days after I reported it on the mailing list.

This page explains rather well what kernel primitives are missing from the CentOS-5 kernel, their impact, and possible fixes.
I'm affraid you're out of luck because of the bit too much aged kernel version of CentOS 5.x. If the go runtime uses features simply not present in that kernel, then I see no easy way how it could work.
you could download the rpm package and begin installing locally, check below and download according to your OS:
http://pkgs.org/download/golang
or you could alternatively compile and build from source:

I have recently installed ipython and have before that installed curses:
jinja2 numpy pexpect pygments qt sqlite3 tornado zmq
I have run iptest just after and got OK at the end. But near the end of the report there was the following:
Tools and libraries NOT available at test time:
azure cython matplotlib oct2py pymongo rpy2 wx wx.aui
My question is whether those listed as not available at test time need to be installed for ipython to run optimally?
Thanks.
Question have already been asked and answerd on ML by other users :

Here is the answer given by MinRK:
No, but some tests of compatibility or extensions, etc. use those, so it's just a note to tell which tests were run.
