python - ImportError on pickle.load for object -

when trying load file pickle getting importerror: no module named application_mgmt.

strangely same file can loaded no problem form different function both use same get_file method , all. strangely can load of other files function.

i have tried moving functions different class/file. clearing , re-populating saved file nothing seems work.

the object in saved file:

 class application():          def __init__(self,name,focus=false):             self.name = name             self.focus = focus              self.prod_score = 5             self.display_name = name             self.color = "none" 

function causes error:

  def check_meta_info(self, app_name):             self.get_file("saved_meta_data") 

file handling function:

 def get_file(self, file_name):         path = "back/saved_data/%s" % (file_name)          try:             open(path,'rb') saved_file:                 saved_list = pickle.load(saved_file)                 saved_file.close()                 return saved_list          except ioerror:             #stuff 

log:

traceback (most recent call last):   file "<stdin>", line 400, in <module>   file "<stdin>", line 221, in app_meta_info   file "<stdin>", line 313, in check_meta_info   file "<stdin>", line 358, in get_file importerror: no module named application_mgmt  shell returned 1   

the function works calls same file class:

 def add_meta_info(self, new_application):          new_meta = application(new_application)  # creates obj          saved_meta_info = self.get_file("saved_meta_data")          metas in saved_meta_info:             if new_meta.name == metas.name:                 return false           saved_meta_info.append(new_meta)         self.save_file(saved_meta_info,"saved_meta_data")         del new_meta

looking @ error log, don't think problem has pickle loading. don't know why he's trying import application_mgmt - line of get_file 358th ? - importerror caused :

• forgetting __init__file in back folder. folder not importable without it. create empty 1 if it's missing.

• python path problem : check if that's problem, try adding @ beginning of get_file method.

  import sys sys.path.append('/path/to/the/back/module/')

• circular imports : if find - between application_mgmt.py , file -, try refactoring code avoid them.

hope helps.
