Solution

One reason why the API may fail to install is due to a bug with the miniconda install that we use. To determine if this is the cause of the issue, open up the csds_install.log file in the CSD_YYYY (where YYYY is the year of the install, e.g. CSD_2021) and search for the phrase "recursion depth". It this reveals an error section alike

then it is likely that you are running into this bug, which is related to erroneous settings of user home environment variables. If you have the error, check your system and user environment variables for HOME entries and ensure they are correct (or removed if not used elsewhere).

If the problem persists, a workaround is to manually install the pip CSD Python API packages, rather than using the conda packages that the CSD Portfolio installer contains.

a) Download the pip package for Windows from the links available to you

b) Start an administrative command line prompt (type cmd in the start menu and right-click to open a command line prompt as administrator)

c) Run

"C:\Program Files\CCDC\Python_API_2021\miniconda\Scripts\activate"

(where the location is the acual location of the Python_API_YYYY folder on your system)

then

"C:\Program Files\CCDC\Python_API_2021\miniconda\Scripts\pip" install "<path-to>\csd-python-api-X.Y.Z-win32-64-py3.7.zip"

(where <path-to> is the location of the file you downloaded in step 1, and X.Y.Z is the version for this release, e.g. 3.0.5).

If you have other modules available in addition to the base CSD Python API package, these can then be installed in the same manner.
