When Trying to import nlp collections in the Nemo Primer getting error "No Module named megatron"
Hi @evodata123, the specific `'ApexGuardDefaults' is not defined` error you are seeing should be fixed by [this PR](https://github.com/NVIDIA/NeMo/pull/9732). But note that Megatron core is a required dependency of NeMo, so if Megatron core is not installed, you may see some orthogonal issues.  This issue is stale because it has been open for 30 days with no activity. Remove stale label or comment or this will be closed in 7 days. This issue was closed because it has been inactive for 7 days since being marked as stale.
This is being done in google colab environment.
with Nemo version 2.0.0rc0
