WPTO Hindcast Issues

In some Python package configurations, the WPTO hindcast functions will not be installed with MHKiT due to an issue with the h5py package. In this case, the error “WARNING: Wave WPTO hindcast functions not imported from MHKiT-Python.” will print to the screen when trying to run any MHKiT function. This is often caused by the h5py package being installed via Anaconda instead of pip. Note: this particular issue only relates to MHKiT-Python users.

If you recieve “AttributeError: module ‘mhkit.wave.io’ has no attribute ‘hindcast’” when trying to run the WPTO hindcast functions:

  1. Make sure your MHKiT package is up to date (see above).

  2. Uninstall h5py from Anaconda

    `conda remove h5py`

  3. Re-install MHKiT:

    `pip install mhkit --upgrade` or `pip install -e . ` from your local clone
