Issue generating flan2021 submix

[Bondrake]

Hello, I have successfully generated other submixes, but for FLAN2021 I am getting stuck on this error:

ERROR:absl:Failed to load task 'bool_q_template_0to10_no_opt_zero_shot' as part of mixture 'flan2021_submix'

I've tried on other systems and also using Python 3.10

Is this an issue with tfds / bool_q? What would the workaround be?

[Bondrake]

Sorry, this seems to be an issue with tfds using cached data that doesn't correspond to bool_q in /root/tensorflow_datasets/downloads/manual/
