Bug in Metal.multitask.mt_end_model, line 114.

[kexiao17]

variable output_dim is used without being defined, the only definition of output_dim in this function is at line 101 inside another if statement.

Ah, you're right! Thanks for bringing this to our attention. With the release of v0.9 of Snorkel (https://github.com/snorkel-team/snorkel), we merged all the best features of MeTaL back into the main repository, including the multi-task end model (and many other major improvements; see https://www.snorkel.org/hello-world-v-0-9/ for details). Snorkel MeTaL is now in maintenance mode, but Snorkel proper is under active development with more support than ever. Take a look at the new MultitaskClassifier in Snorkel (tutorial here: https://www.snorkel.org/use-cases/multitask-tutorial) and let us know if you have any issues!

This should also be fixed now in MeTaL with the merge of PR #211.
