I did a clean install of rasa on ubuntu and I cannot train the sample model.
rasa init works but only if I choose not to train the model. When I choose to train the model I get the warning,
VisibleDeprecationWarning: Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated
and then a tensor flow error
/usr/local/lib/python3.8/dist-packages/tensorflow/python/framework/ops.py:845 __array__ raise NotImplementedError( NotImplementedError: Cannot convert a symbolic Tensor (strided_slice_6:0) to a numpy array. This error may indicate that you're trying to pass a Tensor to a NumPy call, which is not supported
My system is as follows;
