I have some pyhton-scripts which are working perfectly on my local computer, but as you would guess, not so good on the server!

I wanted to use "pythonbrew" since at the server I have only Python 2.7.6 installed, but I need hdf5-package running ... OK

I installed pythonbrew (according to https://pypi.python.org/pypi/pythonbrew/) and switched to version 2.7.10 (as I use on my local computer).

Now I got some "numpy-issues". So I installed numpy with pip successfully (according to How do you install numpy when you're not a superuser? and https://gist.github.com/audy/4012573), however, when I am running the programme:

pythonbrew py startup.py

I got the error message saying numpy was not found ...

I really have no clue what I am missing here? I appreciate any help!

  • It's look pythonbrew no longer in active development. They are suggesting to use https://github.com/yyuu/pyenv. However, if you are going to use numpy heavily in the production environment, I suggest you to use https://www.continuum.io/why-anaconda distribution. It can install without affecting to the system python installation. You can use conda package manager that comes with Anaconda to install numpy – erandac Nov 05 '15 at 18:25

I found out myself how to run a python script with pythonbrew properly!

According installation guide for pythonbrew (see: https://pypi.python.org/pypi/pythonbrew/), the following line should be used to run a script:

pythonbrew py myprogramm.py

However, I can run my script by using python instead of pythonbrew py:

python myprogramm.py

I cannot give an explanation for that, sorry. But maybe other people can. It is just working very well like this and I can use python and all packages normally!

Further instructions of how to use pythonbrew, installing or switching between different version etc., see the link to the installation guide I posted above!

More details about pythonbrew and usage (from my perspective of view):

The installation guide I mentioned explains step by step how to install pythonbrew in your home directory (e.g. on a server) and helps to set up python on a system where you are not superuser (e.g. a server where you are allowed to run scripts but not to execute any further installations!).

I had the problem that I needed a more up to date python-version and the server where the data is located is equipped with an older version. The other half of the story is that I also needed some packages (e.g. h5py or cosmolopy) which are also not installed at the server.

For me the easiest and perfectly working solution to that problems was to use pythonbrew and install it at my home directory on the server!
