[Python] module 'ants' has no attribute 'from_numpy'

pip install antspyx


However, using the function from_numpy throws an error:

import ants

Im2Use=Im[0,:,:,:]
fixed, moving, mytx=reg(Im2Use, t_rz)
fwdtransforms=mytx['fwdtransforms']
fixed_ants= ants.from_numpy(Im2Use.astype(float))
moving_ants= ants.from_numpy(t_rz.astype(float))
mywarpedimage=ants.apply_transforms( fixed=fixed_ants, moving=moving_ants,transformlist=fwdtransforms)
