Getting DimensionMismatch("tried to assign 99-element array to 100×1 destination") error

I am getting the error DimensionMismatch("tried to assign 99-element array to 100×1 destination") when trying to apply wordvectors on a trained word2vec text file.

What exactly does this mean?

No file, test, or entry point is named. Start by reproducing the wordvectors call with the trained word2vec text file and inspect how vector dimensions are read versus the expected 100×1 destination; done means explaining the mismatch and identifying a concrete correction.
