fpgrowth_py's Issues

I need the support of each frequent pattern.

I need the support of each frequent pattern. can you just tell me how to get every pattern's support with it? sth like this:
[{'L' : 4}, {'L', 'M' : 3} , ...]

TypeError: cannot unpack non-iterable NoneType object

from fpgrowth_py import fpgrowth
itemSetList = [['276', '303'],
 ['0', '109', '293', '160', '171'],
 ['204', '49'],
 ['204', '105'],
 ['49', '303', '105', '204', '276'],
 ['261', '255', '154', '74'],
 ['145', '261', '154']]
freqItemSet, rules = fpgrowth(itemSetList, minSupRatio=0.5, minConf=0.5)

TypeError: cannot unpack non-iterable NoneType object

Add support ratio in the fpgrowth's return rules

Your project really help me. But could you please add support ratio in the fpgrowth function's return rules?

The output is wrong when the minConf=1

from fpgrowth_py import fpgrowth
itemSetList = [['eggs', 'bacon', 'soup'],
               ['eggs', 'bacon', 'apple'],
               ['soup', 'bacon', 'banana']]
freqItemSet, rules = fpgrowth(itemSetList, minSupRatio=0.5, minConf=1)
print(rules)

THE EXPECTED OUTPUT RULES SHOULD BE:
[{eggs} -> {bacon}, {soup} -> {bacon}]

BUT THE OUTPUT OF THE ABOVE CODE IS:
[]

this error is found when comparing your package with another package efficient_apriori (see https://github.com/tommyod/Efficient-Apriori)

ModuleNotFoundError

hi, run the pip installation, but still gives me "ModuleNotFoundError: No module named 'fpgrowth_py'".
Any help? Thanks!
