Is there any limit for the vocab size (#types)?

[rasoolims]

The code fails (with core dump: segmentation fault message) when I run it on a huge txt file (about 20M types and 14GB file size). I already used wcluster for different files with much less types and it worked pretty well.

I'm not sure what the exact limit is but I'm not surprised that it failed
with 20M types. You can try using the restrict command line option to
restrict it to a smaller vocabulary. The brown clustering algorithm dates
back to a time when people didn't have 14GB text files to work with.

I have noticed that at the end of March a new commit was performed. The commit is labeled "Enable >= 2^31 tokens in input data" so I thought it would have addressed the issue raised here. However, I still ran into an issue similar to the one mentioned by rasoolims. I'm able to successfully run the code only with a file containing 10M tokens (700K types). With bigger files it fails saying "core dump: segmentation fault".
Any suggestion?

thanks

Did you try using the flag to restrict the vocabulary?

Do you mean the min-occur flag?
It seems to have an impact only on efficiency.

I know this is late and probably not important to OP anymore but for any other people facing the same issue, this pr fixed the issue for me.
