2 years ago The problem is that we iterate recursively through the data in the multiprocessing hashing. So the maximum recursion depth is reached if there is more data than max_recursion_depth max_sample n_processors. I've fixed this by using a while loop instead of recursion
Expected Behavior
no erros during hashing
Actual Behavior
following error is thrown: Traceback (most recent call last): File "/usr/lib/python3.8/multiprocessing/process.py", line 315, in _bootstrap self.run() File "/usr/lib/python3.8/multiprocessing/process.py", line 108, in run self._target(*self._args, **self._kwargs) File "/home/user/.local/lib/python3.8/site-packages/category_encoders/hashing.py", line 162, in require_data self.require_data(self, data_lock, new_start, done_index, hashing_parts, cols=cols, process_index=process_index) File "/home/user/.local/lib/python3.8/site-packages/category_encoders/hashing.py", line 162, in require_data self.require_data(self, data_lock, new_start, done_index, hashing_parts, cols=cols, process_index=process_index) File "/home/user/.local/lib/python3.8/site-packages/category_encoders/hashing.py", line 162, in require_data self.require_data(self, data_lock, new_start, done_index, hashing_parts, cols=cols, process_index=process_index) [Previous line repeated 954 more times] File "/home/user/.local/lib/python3.8/site-packages/category_encoders/hashing.py", line 157, in require_data hashing_parts.put({part_index: data_part}) File "", line 2, in put
