Error while adding aliases to KnowledgeBase while training Entity Linker

[shrinidhin]

Hi!I am training a custom Entity Linker component and creating a Knowledge base for the same using the following code:

for a, qids in alias_dict.items():
        kb.add_alias(alias=a,entities=qids,probabilities=[0.5])

where alias_dict is a dictionary with aliases as keys and a list of entities for each alias as keys. For eg, if entities B and C have aliases 'a', then
alias_dict['a']=['b','c']

Now I get the following error while trying to add them:
ValueError: [E132] The vectors for entities and probabilities for alias should have equal length, but found 2 and 1 respectively.
What does this mean exactly?Does it mean that both entities have same vectors?

The entities argument must be the same length as the the probabilities argument. So if your qids has a length of two then your probabilities should be [0.5, 0.5] or something, not just [0.5].

Oh I see what I did wrong!Thank you!
