dimension mismatch oltw arzt #30
Description
for scalar-valued sequences the squeeze in the OLTW Arz step function input_features.squeeze(-1) returns a scalar with dimension 0 which is not accepted by the cythonized distance function.
the cythonzed distance function also expect a one-dimensional input -> a single frame input, for higher step sizes this breaks as the inputs either can't be squeezed for vector-valued frames, or the sequence of scalar values is treated as a single vector-valued frame and only the distances with resüpect to its first member is computed.
