NeuroKit: ecg_process() function ValueError: NeuroKit error: we expect the user to provide a vector, i.e., a one-dimensional array (such as a list of values). Current input of shape: ()

Hi, In the python 3.7 - 32 bits environment i have run the following sample code given for ecg_process function.

>>> import neurokit2 as nk
>>>
>>> ecg = nk.ecg_simulate(duration=15, sampling_rate=1000, heart_rate=80)
>>> signals, info = nk.ecg_process(ecg, sampling_rate=1000)

When i run the nk.ecg_process() statement (signals, info = nk.ecg_process(ecg, sampling_rate=1000)) i received the following error.

when i run in 64 bit python environment this statement is working fine. Why it is giving error in 32_bit environment
