libcasadi_interpolant_linear.dll not found #3696

Hi everyone, I keep receiving this error, although I checked the Lib\site-packages Folder and the mention dll is definitely there:

RuntimeError: .../casadi/core/casadi_os.cpp:166: Assertion "handle!=nullptr" failed: PluginInterface::load_plugin: Cannot load shared library 'libcasadi_interpolant_linear.dll': ( Searched directories: 1. casadipath from GlobalOptions

  1. CASADIPATH env var
  2. PATH env var (Windows)
  3. LD_LIBRARY_PATH env var (Linux)
  4. DYLD_LIBRARY_PATH env var (osx) A library may be 'not found' even if the file exists:
    • library is not compatible (different compiler/bitness)
    • the dependencies are not found ) Tried 'C:\Users\Schätzelein\Documents\Forschungspraxis\Model\myenv\Lib\site-packages\casadi' : Error code (WIN32): 126 Tried '' : Error code (WIN32): 126 Tried '.' : Error code (WIN32): 126

I have Python 3.11.9 64-bit and currently want to run a model with PyBamm. Does anyone encounter the same issue?

Hi, @L0tusC00kie – this was fixed in https://github.com/pybamm-team/PyBaMM/pull/4077 and will be available in the v24.5 pre-releases and subsequent stable release.
