TypeError: 'NoneType' object is not subscriptable

[Reza]

Hi jiba
I have below code :

"
default_world.set_backend(filename = "pym.sqlite3")
import_umls("umls-2019AA-full.zip", terminologies = ["ICD10", "SNOMEDCT_US", "CUI"])
default_world.save()
default_world.set_backend(filename = "pym.sqlite3")
PYM = get_ontology("http://PYM/").load()
print(type(PYM))
SNOMEDCT_US = PYM["SNOMEDCT_US"]
concept = SNOMEDCT_US[186675001]      =>> line 12
print(concept)

"
my error is :
"
Traceback (most recent call last):
  File "C:/ReportClassification/OWLready2.py", line 12, in <module>
    concept = SNOMEDCT_US[186675001]
TypeError: 'NoneType' object is not subscriptable

"

Can you guide me?
thank you

Hi,

The error message suggest that PYM["SNOMEDCT_US"] is None. Are you sure the UML importation worked well ? Could you send me the output of the importation, to check it, please?

I run the following code :
"
from owlready2 import *
from owlready2.pymedtermino2 import *
from owlready2.pymedtermino2.umls import *

default_world.set_backend(filename = "pym.sqlite3")
import_umls("umls-2019AA-full.zip", terminologies = ["ICD10", "SNOMEDCT_US", "CUI"])
default_world.save()
# default_world.set_backend(filename = "pym.sqlite3")
PYM = get_ontology("http://PYM/").load()
SNOMEDCT_US = PYM["SNOMEDCT_US"]
concept = SNOMEDCT_US[186675001]
print(concept)

"

Its output is as follows :

"

Hi,

The UMLS importation do not list any parsed .RFF files, so nothing was imported.

Could you try with the development version of Owlready (on Bitbucket)?

In general, the error means that you attempted to index an object that doesn't have that functionality. You are trying to subscript an object which you think is a list or dict, but actually is None. NoneType is the type of the None object which represents a lack of value, for example, a function that does not explicitly return a value will return None. 'NoneType' object is not subscriptable is the one thrown by python when you use the square bracket notation object[key] where an object doesn't define the __getitem__ method .
