MemoryError while running on a 50 item transactions

Open edoniti opened this issue 7 years ago • 2 comments

I have a list of 30 transactions with up to 50 items per transaction. I am having the following MemoryError problem. I am running on Python 3.6, my PC has 4GB of RAM.

Is there any solution to this? To make it work with this number of items per transactions?

Traceback (most recent call last): File "C:/Users/Edoniti/PycharmProjects/Project/fp-growth/fp-growth1.py", line 15, in <module> patterns = pyfpgrowth.find_frequent_patterns(transactions, 2) File "C:\Users\Edoniti\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pyfpgrowth\pyfpgrowth.py", line 253, in find_frequent_patterns return tree.mine_patterns(support_threshold) File "C:\Users\Edoniti\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pyfpgrowth\pyfpgrowth.py", line 155, in mine_patterns return self.zip_patterns(self.mine_sub_trees(threshold)) File "C:\Users\Edoniti\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pyfpgrowth\pyfpgrowth.py", line 235, in mine_sub_trees subtree_patterns = subtree.mine_patterns(threshold) File "C:\Users\Edoniti\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pyfpgrowth\pyfpgrowth.py", line 155, in mine_patterns return self.zip_patterns(self.mine_sub_trees(threshold)) File "C:\Users\Edoniti\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pyfpgrowth\pyfpgrowth.py", line 235, in mine_sub_trees subtree_patterns = subtree.mine_patterns(threshold) File "C:\Users\Edoniti\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pyfpgrowth\pyfpgrowth.py", line 155, in mine_patterns return self.zip_patterns(self.mine_sub_trees(threshold)) File "C:\Users\Edoniti\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pyfpgrowth\pyfpgrowth.py", line 235, in mine_sub_trees subtree_patterns = subtree.mine_patterns(threshold) File "C:\Users\Edoniti\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pyfpgrowth\pyfpgrowth.py", line 153, in mine_patterns return self.generate_pattern_list() File "C:\Users\Edoniti\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pyfpgrowth\pyfpgrowth.py", line 193, in generate_pattern_list min([self.frequent[x] for x in subset]) MemoryError
