Windows Installing Guide for PandExo

Created by J. N. van Haastere (Physics and Astronomy Bachelorstudent) Univesity of Amsterdam and VU University Amsterdam

Step 1

You may want to uninstall older python versions to prevent troubles along the way.

Step 2

Download most recent Anaconda version (tested with Python 3.6.4 64 bit)

Step 3

Install Anaconda as main python and add to path environment


If succesfully installed you can open CMD and type >>python and >>quit() to check version

Step 4

Install Build Tools for Visual Studio 2017.

Step 5

Follow PandExo Installation guide in getting files

  • get pandeia_data

  • get pysynphot_data (includes phoenix models and throughputs)

Step 6: Setting Reference Data

Using an achiver (eg. Winrar, 7Zip) extract Pandeia and Pysynphot data in two seperate folders.


Check the variable names

echo 'export VARIABLE_NAME = ".."'

In case nothing changes these should be PYSYN_CDBS & pandeia_refdata

Set these in Windows environment variables / registry using SETX. Open CMD or Anaconda Prompt and run:

SETX PYSYN_CDBS 'C:/Users/USERNAME/pysynphot_data'
SETX pandeia_refdata 'C:/Users/USERNAME/pysynphot_data'

You can check this step by opening a new CMD and run > SET

Step 7: Installing needed Packages

Install PandExo Engine

pip install pandexo.engine

Check troubleshooting if you run into problems. Troubleshooting here.

Step 8: Run Test

Navigate to your pandexo-master and run the run_test. Check in the installation guide on the exact expected output.

cd '...'

Congrats on being persevering/stubborn enough to get it on to work on Windows! There are some test Jupyter files to try out in pandexo-master/notebooks
