Set `SYMPY_USE_CACHE` environment variable to "no" #684

Closed thisac closed 2 years ago

thisac commented 2 years ago

Context: Quick fix for an issue with SymPy caching expressions and wrongly using a cached register reference instead of the new one. See issue #683 for details.

Description of the Change: Sets the SYMPY_USE_CACHE environment variable to "no" in CI, so that no caching is done when running tests.

Benefits: Certain cases when SymPy parameters are cached and incorrectly retrieved will (hopefully) no longer happen in the CI tests.

Possible Drawbacks: This is just a quick fix for the CI tests. The issue is still present in the code-base.
