Hello When I run the example file "301_Kalman_2DOF_5States" and "300_Kalman_2DOF_7States", the process abort. The run output showes that:

Change the code in TNLin.py, line 239 and line 411 z_test = list(fastlib.ED_TwrGag(KF.WT.ED)[-1] - KF.WT.ED['TowerBsHt'])

The issue is closed.

Hi,

Thanks for reporting this. In fact, you would need to ensure the TwrGag is a numpy array instead of a list. You can do this with np.asarray. Feel free to submit a pull request.
