I have a CentOS 7.4 GPU machine.
I tried to install cntk in the machine. I cannot use the pip files as they are for ubuntu (I tried to install with them and get seg fault when I import cntk).
I compiled the cloned cntk successfully. However I when I try to get the python version, I run into troubles. I did
sudo python setup.py install
in $cntk_root/bindings/python
and get
building '_cntk_py' extension
swigging cntk/cntk_py.i to cntk/cntk_py_wrap.cpp
swig -python -c++ -D_MSC_VER -I../../Source/CNTKv2LibraryDll/API -I../../bindings/common -Werror -threads -o cntk/cntk_py_wrap.cpp cntk/cntk_py.i
cntk/cntk_py.i:92: Error: Syntax error in input(1).
error: command 'swig' failed with exit status 1
It must be simpler than this. Suggestions?
I can't help with your above problem but if you relax the constrain of not using Conda and follow these instructions I can say that it will work since I did it a few weeks ago on RHEL 7 using the cntk release 2.2.
Note, release 2.2 assumes that /var/lock is writable which is not true for me. If you follow the instructions above you need to open CrossProcessMutex.h and replace /var/lock/ by a writable directory.

I was trying to install opencv for python using this link. After running the Cmake command, it exited with errors stating C++11 is not supported Although I have Xcode installed. I Also tried forcing Cmake to use C++ 11 using $ set(CMAKE_CXX_STANDARD 11) (because my Cmake version is 3.10.2), but I got this error:
syntax error near unexpected token `CMAKE_CXX_STANDARD'
Moreover, I tried installing gcc to check if my system supports the C++ 11 compiler through this link, where again I ran into terminal errors stating ./fixincludes: No such file or directory after running $ make install . What should I do?
Adrian has a more recent blog post on compiling OpenCV for the macOS. The instructions work both for 3.3.0 and 3.3.1.
First open python by python2 or python3 command in terminal after type import cv2 and everything is right now.
Before I get to far into this, I should note that I have seen a very similar question, but the solution presented did not work for me. Perhaps one reason why is because that was Linux build and my current difficulty is on a Windows 7 machine. I use Cygwin to get access to the gcc (5.2.0) compiler suite.
In any event, I have been attempting to try out Stan via PyStan. I am working with an Anaconda (2.4.1 64-bit) distribution which I just updated today (Python 2.7.11). I initially tried to install PyStan via pip, but the install keeps failing due to what looks like the following error:
Cannot build msvcr library: "msvcr90d.dll" not found
Consequently, I used conda instead, which seemed to install just fine. (I should note that the conda install pushed my numpy back to an earlier version, which created conflicts with the pandas upon import. I just updated anaconda to deal with these broken dependencies.) I was also able to import PyStan without any problems. However, when I actually tried to fit a model (inside of a Jupyter Notebook), the process failed with the exception in the title.
The first thing I did was confirm that gcc was where in the referenced location (not shown in the title). Indeed it was, and it seemed to working just fine. I then tried to run the model as a script from the command line (still using Python), and it failed with the same error. When I recreated the model via the REPL, it pointed to a different location that had a .bat file referencing the (verified) compiler, and that failed as well.
I am pretty sure this is because I have Visual Studio 2012, instead of Visual Studio 2008. While it is possible for me to run parallel installations, if this code is going to be useful for others in the future, these are not reasonable hoops to jump through to make it happen. I was hoping that someone else might have a better explanation. Any info would be greatly appreciated.
Beneficial from the post at https://github.com/stan-dev/pystan/issues/306
I have met various error message, but finally, I install PyStan successfully.
My machine is also on Windows 7, x64 with Anaconda3 installed.Here are the procedures to install PyStan from the sourced codes.
Install Visual Studio 2017 & Visual Studio C++ Build Tool 2015 at http://landinghub.visualstudio.com/visual-cpp-build-tools
Update Conda
conda update conda
conda update --all
check the dependencies
pip install setuptool
conda install numpy cython matplotlib scipy pandas
Install gcc compiler components
conda install libpython
conda install -c msys2 m2w64-toolchain=5.3.0
created distutils.cfg file inside Anaconda3\Lib\distutils folder with the following:
[build]
compiler = mingw32
Download Git at https://git-scm.com/downloads
git clone --recursive https://github.com/stan-dev/pystan.git
Compile from the source code
python setup.py build --compiler=mingw32
python setup.py install
P.S. The solution for the issue: Cannot build msvcr library: "vcruntime140d.dll" not found.
Copy vcruntime140d.dll from C:\Windows\System32 to any folder, which is reachable in the path in the advanced system settings/environment variables/ system variables.
I'm trying to install Theano on Enthought Python Distribution (EPD), but I am getting a weird error. Here is what my installation looks like:
I have installed EPD to C:\Python27.
After that, I have installed pip by using easy_install pip
I installed Theano by using pip install Theano
To test, I start ipython and type import theano. I get the following error:

Does anyone know how to get Theano to run with EPD?
The last release of Theano(0.5) has some problem on Windows. You need to install the bleeding edge version. You can update your version like this:
pip install --upgrade --no-deps git+git://github.com/Theano/Theano.git
This should solve the problem. If not, you probably have some conflict with a different installation of gcc. Do you have installed it with cygwin or mingw? EPD installs its own version of mingw.
I couldn't get Theano working with Enthought, but using the Anaconda python distribution I eventually got it working. Here's how:
uninstall Enthought and any other python version (start from scratch)
download and install Anaconda python distribution from this link: http://09c8d0b2229f813c1b93-c95ac804525aac4b6dba79b00b39d1d3.r79.cf1.rackcdn.com/Anaconda-1.5.0-Windows-x86_64.exe and click the option to use Anaconda as your default python version
to get the academic license, go to this page: https://store.continuum.io/cshop/academicanaconda and click the "free" button next to Anaconda Academic License (right side of page)
you should receive an email with an academic license .txt file. Follow the instructions in the email to place the file in the correct directory, and run several command-line commands to update anaconda and install numpy and scipy
open a windows command prompt and type
pip install theano
create a file .theanorc.txt containing the lines:
[global]
openmp=False
[blas]
ldflags=
place .theanorc.txt in your home folder (the folder for your user account)
make sure the following paths are added to your PATH environment variable:
C:\Anaconda\MinGW\bin;
C:\Anaconda\MinGW\x86_64-w64-mingw32\lib;
C:\Anaconda;
C:\Anaconda\Scripts;
I am setting up os X 10.7.
I am using the default install of Python:
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/
I use a Python based package manager called easy_install.
Easy_install seems to not be able to find the compiler.
EDIT: When I tried to install MySQL-python I got this error:

Xcode 4.1 used GCC, but with Xcode 4.2 that seems to have changed.
What compiler does Apple want us to use?
How do I setup the configuration so I can compile OSS?
I had the exact same problem when I upgraded from OSX 10.6 to 10.7. If you upgrade to 10.7 from 10.6, your version of Python may go from 2.6 to 2.7 and a result you may need to re-install most of your python packages.
Here's what worked for me:
Install the latest version of XCode from the App Store
Inside XCode, go to Preferences -> Downloads -> Components
download the Command Line Tools
That's all you need to do. Try to install again in a new shell. The command line tool installation will put llvm-gcc-4.2 into /usr/bin which should be in your default path. The installation also takes care of library paths and stuff that you don't really want to know about unless something breaks.
10.9 edit
If you're running 10.9 or higher, I think you might be able to run this from the command line instead to install the command line tools:
xcode-select --install
I haven't verified that this is an actual fix to the problem.
Alternative to installing Xcode, install GCC and related tools via:
https://github.com/kennethreitz/osx-gcc-installer
Sounds to me you ran into this issue. The thread shows a variety of solutions.
Hope that helps.
The fix is quite simple. Check out the following blogpost.

Using OS X 10.7.5 (Lion)
I tried the XCode solution, but my gevent pip installation still wasn't successful. Then, I tried building libevent from source but still no success with gevent installation. However, after I did
brew install libevent
I was able to successfully install gevent with
sudo pip install gevent
(Note: greenlet is also a dependency for gevent, so you may try installing it with pip as well. It was already installed on my machine.)
All of the suggestions here (Xcode command line options, and Kenneth Reitz' stuff) didn't work for me (I am on Mac OS X 10.7.5, Xcode 4.6.3).
What helped in the end was altering the cflags options in the mysql_config file (There were errors about 'unreconized command line options' while trying to 'sudo pip install MySQL-python').
See this post: cc1: error: unrecognized command line option "-Wno-null-conversion" within installing python-mysql on mac 10.7.5
I am setting up Python and Django on os X 10.7 from a virgin install and Xcode 4.3.
I tried using the default install of Python:
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/
I normally use a Python based package manager called easy_install.
Easy_install seems to not be able to find the compiler.

Apparently, the system attempts to use the same compiler used to compile the installed Python framework.
For some reason Apple didn't include llvm-gcc-4.2.
Xcode 4.1 used GCC, but with Xcode 4.3 that seems to have changed.
From what I can gather, Apple wants to use Clang as the compiler vs GCC.
So I added to .bash_profile:
cc=clang
I decided I would just recompile Python with clang but first, I needed to install readline.

What the easiest way to install Django on Lion 10.7?
Did you install the command-line tools with Xcode 4.3? They are not installed by default. You can install them by going to the Downloads pane in Xcode 4.3's preferences.
Making it way too hard:
First, make sure you install Xcode (available for free in the Mac App Store). It includes all the build tools that might be necessary to compile certain Python packages.
To get easy_install just download setuptools and follow the instructions for installing on Mac OS X at that link.
Once that's done, you can easy_install virtualenv to get a nice segregated environment to work in.
For the MySQL issue you have to edit the site.cfgfile:
mysql_config = /usr/local/mysql/bin/mysql_config
And then:
$ python setup.py build
$ sudo python setup.py install
Try updating XCode and reinstall all global site-packages. You may also want to try pip instead of easy_install.
You can also try to compile with
export ARCHFLAGS='-arch i386 -arch x86_64'
This solved many of my problems in the past when upgrading OSX versions.
