Obtaining and Installing Software
JWST calibration pipeline software is currently under development. It is not yet supported for public use.
When the software is publicly released, it will be available in AstroConda, which is a free Conda channel maintained by the Space Telescope Science Institute (STScI) in Baltimore, Maryland. Until then, it can be obtained from the GitHub repository in which it is maintained. Instructions for installing it are available at its GitHub repository.
Please note that this software is still under active development; it is offered on an as-is basis with no guarantee of correctness or support.
