Limitation of: Data size of one of transform dimensions exceeds 2^31 - 1 bytes

[JesseLivezey]

Based on the error message, it seems like this is a known limitation, but I'm resampling data using ffts and get an error related to the size of the data. The data shape is: (17863680, 128) and the fft is being taken along axis=0.

I'm guessing this might be related to an index being int32, and if it is possible to get rid of this limitation, that would be helpful.
