Simply running this line `from transformers import DataCollatorForLanguageModeling` gives me a `Bus error (core dumped)`.
I’m using `transformers==4.23.1` and `python==3.9.12`. What could be the cause of this error?

My `/dev/shm` was full apparently. After increasing the size of it by running `mount -o remount,size=25G /dev/shm`, the import worked just fine. I’ve no idea why this particular import statement uses `shm` though

How much should be the minimum /dev/shm. I have 8GB and it is empty. I am still getting Bus Error while importing sentence\_transformers.
