Windows Installing Guide for PandExo¶
Created by J. N. van Haastere (Physics and Astronomy Bachelorstudent) Univesity of Amsterdam and VU University Amsterdam
You may want to uninstall older python versions to prevent troubles along the way.
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
- get pandeia_data (pandeia_data-1.2.tar.gz)
- get pysynphot_data (synphot5.tar.gz)
- get PandExo github folder (pandexo-master.zip)
Open pandexo.sh in your favorite text editor (eg. Notepad++) and read through installation steps. Below we will follow these steps but with Windows commands.
Step 7: 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¶
Add conda channel, in CMD:
conda config --add channels http://ssb.stsci.edu/astroconda
Check needed packages, at the moment:
numpy synphot joblib scipy astropy==2.0.2 pyfftw pysynphot photutils sphinx=1.5.6 bokeh=0.12.6
All but Pyfftw can be installed using:
conda install PACKAGE
pip install PACKAGE
If they fail check in the error if you are missing a certain .dll or look online.
For Pyfftw get a prebuiled wheel from here.
Get a matching cp36-cp36 for your python version. For Python 3.6.4 64-bit I used:
Navigate to download folder and install
cd 'C:\Users\USERNAME\Downloads' pip install pyFFTW-0.10.5.dev0+d45d7fe-cp36-cp36m-win_amd64.whl
With your fingers crossed, install PandExo Engine
pip install pandexo.engine
Probabily fail, look what I/you missed and try again. 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 '...' python run_test.py
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
