I'm trying to run cython with Python2.7 installed using OSX running Mountain Lion but I get the following errors:
Traceback (most recent call last):
File "/usr/local/bin/cython", line 5, in <module>
from pkg_resources import load_entry_point

raise DistributionNotFound(req) # XXX put more info here
pkg_resources.DistributionNotFound: Cython==0.17
How can I fix this?
Thanks!
Probably what happened is that you installed cython with one version of python and are trying to run it with another. Rather than doing the standard
python setup.py build
sudo python setup.py install
Try just switching to root and both building and installing using an explicit version of python:
sudo su
/usr/bin/python setup.py build
/usr/bin/python setup.py install
(Note that this all assumes that you're installing from a source tarball).

ImportError: libcusolver.so.8.0: cannot open shared object file: No such
file or directory
Failed to load the native TensorFlow runtime.
See https://www.tensorflow.org/install/install_sources#common_installation_problems
for some common reasons and solutions. Include the entire stack trace
above this error message when asking for help.
I have also set my environment variables like this:
export CUDA_HOME=/opt/cuda
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$CUDA_HOME/lib64:$CUDA_HOME/extras/CUPTI/lib64"
Moreover, I found that libcusolver.so.8.0 is not there, while libcusolver.so.7.5
is there in cuda/lib64/.
Somehow tensorflow is finding wrong file or I ain't know nothing.
Any help would be appreciated as I am new to all this stuff.
Python version: 2.7
OS: Linux
This may be connected to the incorrect linking of your libraries.
Simply run sudo ldconfig /usr/local/cuda/lib64. It solved for me.
If you need to know more: ldconfig man page.
I solved the issue. Actually I have cuda 7.5 installed and I was installing latest tensorflow version which probably support cuda 8.0.
So I downgraded.
pip install --upgrade \ https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.10.0-cp27-none-linux_x86_64.whl
If you installed tensorflow-gpu by using pip with prebuilt .whl, the cuda version were fixed. As far as I know, starting 0.11.0rc1, all the prebuilt packages are now built for cuda 8. So there are two ways to solve the problem:
install cuda 8 for the prebuilt packages tensorflow-gpu >= 0.11.orc1
keep cuda 7.5 stay, then build tensorflow-gpu from source code
If you are using cuda-9.0 try sudo apt install nvidia-cuda-dev (if you are using an Ubuntu distribution)
Okay, so I am trying to install libspatialspatialindex to my Ubuntu machine python. I did follow all the instructions and downloaded libspatialindex1_1.4.0-1.1_amd64.deb from http://packages.ubuntu.com/lucid/libspatialindex1 and downloaded the amd64 version of it as my machine is 64bits machine. I installed it and then jumped to Rtree python https://pypi.python.org/pypi/Rtree to download and install the Rtree in python. I followed the installation instruction given in the install.txt file inside the folder. It says run the local setup.py by $ python setup.py install I did that as well but what I get after that is

Can somebody please help me in resolving this issue!
I really appreciate in advance!
You have to install the package "libspatialindex-dev" with the systems package manager. At least this is true with my system (Mint 17.1) which should be 100% compatible to a default Ubuntu installation.
You have to install libspatialindex-dev in your ubuntu system. Here i am using ubuntu 16.04 or 18.04
sudo apt update
sudo apt install libspatialindex-dev
install Rtree using your python pip version, i have pip 3.7
pip3.7 install Rtree
import rtree
Hi i have installed the Scikit-learn but i keep getting error msgs when i try to import the sklearn module. it shows the following msg. anyone knows what's going on?

Contents of sklearn/__check_build:

___________________________________________________________________________
It seems that scikit-learn has not been built correctly.
If you have installed scikit-learn from source, please do not forget
to build the package before using it: run `python setup.py install` or
`make` in the source directory.
If you have used an installer, please check that it is suited for your
Python version, your operating system and your platform.
As you can see in your errors: ImportError: No module named _check_build in that directory it has .c file and it never compiled.
If you check this link you will see many parts of scikit-learn has been written in C.
So for installing this kind of packages , you need to install python-dev package in your system.
python-dev package will install many C headers like python.h.
So install python-dev package in your system and then remove and install scikit-learn package again.
I've got a py2.7 project which I want to test under py3.2. For this purpose, I want to use virtualenv. I wanted to create an environment that would run 3.2 version internally:
virtualenv 3.2 -p /usr/bin/python3.2
but it failed. My default python version is 2.7 (ubuntu default settings). Here is virtualenv --version 1.10. The error output is:
Running virtualenv with interpreter /usr/bin/python3.2

I don't know what the hell is this syntax error - where does it come from... I know there was a change in try...catch statement syntax between 2.x and 3.x, but should virtualenv throw syntax errors?
I'd be grateful if someone pointed me out if there's something I'm doing wrong or if there is an installation problem on my machine.
To create a Python 3.2 virtual environment you should use the virtualenv you installed for Python 3.2. In your case that would be:
/usr/bin/virtualenv-3.2
You'll have to use a Python 3 version of virtualenv; the version you are using is installing Python 2 tools into a Python 3 virtual environment and these are not compatible.
virtualenv --python=/usr/bin/python3.2 --no-site-packages ENV
I have two python versions on my server namely 2.4 and 2.7. It is running RHEL 5.8.
I already have pip and easy_install installed on my server.
When I try to install ipython using easy_install or pip, it gives me an error which probably does not support in python 2.4.
I want to use python 2.7 for both pip and easy_install since I would want to use the latest version of the both.
What should I do to have pip and easy_install use python 2.7. Python 2.4 is installed by default by the system and I do want to keep it.
Python 2.7 is installed at another location.
Below is the traceback both for easy_install and pip. Both end up in the same error. Any kind of help is appreciated.

One way would be:
Open pip/easy_install in text editor
Check top line, it should say
#! /usr/bin/python
Change it to #!path/to/python2.7
You should check this SO question.
You may also want to consider using virtual environment through virtualenv and virtualenvwrapper to manage which version of Python your packages should use.
