error running matlab python package with imwarp function

We're exporting two matlab functions as python packages. One works fine, the other produces a long error message centering on the imwarp function. Both functions work find when exported as standalone applications. The error appears below. Any thoughts? Thanks!

Undefined variable “images” or class “images.internal.imlincombc”.
