GSAS-II with Python 3.x
Here are some instructions for installing Python 3.6 for GSAS-II
Windows
Install Miniconda from https://repo.continuum.io/miniconda
- Download and run the Miniconda3-latest-Windows-x86_64.exe file. The installer will ask you to exit all applications. This is probably not needed but saving your work in all apps before continuing seems like a good idea.
- You will need to accept the license agreement.
- Select "Just Me" unless you want to run Python from multiple accounts on your computer and are logged into an admin account. Use of "Just Me" is recommended.
- Select the installation location with some care. Avoid any path that contains a space in it (avoid C:\Users\Brian Toby\Miniconda3). I suggest C:\conda3. Make a note of the path you use and change subsequent commands to use this path if you use something else.
- Unselect both of the two "Advanced option" boxes unless you are planning to do your own development in Python and understand what they do.
- Click on "Install" and wait a few minutes while the minimal Python files are unpacked and are installed on your computer.
- On the Thanks page, you may want to unselect the two boxes, but do note that the Anaconda folks are doing a great service for science.
Start a Command window
In the start menu, look for an Anaconda3 Windows menu item and select the "Anaconda Prompt" item.
- This will start a cmd.exe window where Python and other Anaconda-installed tools are in the path.
- If for some reason this command is not available. Do this:
- Open a "Command Prompt" window and type c:\conda3\Scripts\activate into that window to set up the Anaconda environment.
Update the Python installation
Type this command:
conda update --all
- you will be given a list of packages that have been updated since the miniconda file was created, press enter at the Proceed prompt to perform the update. This may take a few minutes.
Add other needed packages
Type this command:
conda install matplotlib pillow pyopengl scipy svn h5py pywin32
- You will be given a list of packages to be downloaded and installed, press enter at the Proceed prompt to perform the install. This will take at least a few minutes.
Install the wxPython package =
Type this command:
pip install wxpython
- a 23 Mb file is downloaded and installed. This usually takes less than a minute.
Install GSAS-II
- Download a script to install GSAS-II from this location:
