Installation

Dependencies

You must have already installed the following packages on your computer:

  • numpy
  • pyGRBaglow (if you want to simulate GRB afterglows)
  • pyETC

pyETC and pyGRBaglow can be found on their github repositories. Install pyGRBaglow before pyETC.

Create python environment (optional but advised)

This will create locally a python environment in which you can install and specify the required libraries. The advantage is that it will avoid you to change the libraries version you are using for other projects. You need to install conda first:

Then to create the python environment, open a terminal and type:

conda create --name colibri python=3  numpy

We named this environment colibri as this the telescope for which we use this Image Simulator, but you can use an other environment name.

Once it is installed, type in a terminal (if you let colibri as the environment name, otherwise write the one you chose):

source activate colibri

It will activate the environment. You can see that (colibri) is added in front of your ID in your terminal. If you type “conda list” you can check which libraries and version are installed. When you want to exit this environment type “source deactivate”.

Installation from sources

The sources for ImSimpy can be downloaded from the Github repo.

You can either clone the public repository:

$ git clone git://github.com/dcorre/ImSimpy

Or download the tarball:

$ curl  -OL https://github.com/dcorre/ImSimpy/tarball/master

Once you have a copy of the source, if you created a python environment, do not forget to activate it with:

source activate colibri

Before installing it, remember that you need numpy and pyETC to be installed, as well as pyGRBaglow if you want to simulate GRB afterglows.

You can now install it with:

$ python setup.py develop

Set environment variable

Create an environment variable, ImSimpy_DIR, corresponding to the directory where you want to install the project.

  • For Ubuntu:

Open the .bashrc file and add the following line at the end:

# add a directory for the ImSimpy package  (change the path name accordingly to yours)
export ImSimpy_DIR="/home/dcorre/code/ImSimpy"

Then type source .bashrc in the terminal to take the changes into account, or open a new terminal.

  • For windows:

Right click on My Computer -> Properties -> Advanced System settings -> Environment Variables

Add variable ImSimpy_DIR with value “/home/dcorre/code/ImSimpy” (change the path name accordingly to yours)

Then close and open the terminal again to update the modifications (for windows only)

  • For Mac: ???
