type error in functions to run point in polygon query on RAPIDS - python-3.x

Question

I want to create a point in polygon query for 14million NYC taxi trips and find out which of the 263 taxi zones the trips were located.
I want to the code on RAPIDS cuspatial. I read a few forums and posts, and came across cuspatial polygon limitations that users can only perform queries on 32 polygons in each run. So I did the following to split my polygons in batches.
This is my taxi zone polygon file

There are 263 polygons/ taxi zones in total - I want to do queries in 24 batches and 11 polygons in each iteration.
def create_iterations(start, end, batches):
iterations = list(np.arange(start, end, batches))
iterations.append(end)
return iterations
pip_iterations = create_iterations(0, 264, 24)
#loop to do point in polygon query in a table
def perform_pip(cuda_df, cuspatial_data, polygon_name, iter_batch):
cuda_df['borough'] = " "
for i in range(len(iter_batch)-1):
start = pip_iterations[i]
end = pip_iterations[i+1]
pip = cuspatial.point_in_polygon(cuda_df['pickup_longitude'], cuda_df['pickup_latitude'],
cuspatial_data[0][start:end], #poly_offsets
cuspatial_data[1], #poly_ring_offsets
cuspatial_data[2]['x'], #poly_points_x
cuspatial_data[2]['y'] #poly_points_y
)
for i in pip.columns:
cuda_df['borough'].loc[pip[i]] = polygon_name[i]
return cuda_df
When I ran the function I received a type error. I wonder what might cause the issue?
pip_pickup = perform_pip(cutaxi, cusptaxizone, pip_iterations)
TypeError: perform_pip() missing 1 required positional argument: 'iter_batch'

Answer 1

It seems like you are passing in cutaxi for cuda_df, cusptaxizone for cuspatial_data and pip_iterations for polygon_name variable in perform_pip function. There is no variable/value passed for iter_batch defined in perform_pip function:
def perform_pip(cuda_df, cuspatial_data, polygon_name, iter_batch):
Hence, you get the above error which states that iter_batch is missing. As stated in the above comment as well you are not passing the right number of parameters for perform_pip function.
If you edit your code to pass in the right number of variables to perform_pip function the above mentioned error :
TypeError: perform_pip() missing 1 required positional argument: 'iter_batch'
would be resolved.
