The error message means you are running out of RAM.

With 6 million rows and 6 columns, the size of the data array is (only)
274 MiB. I have no problem allocating it on my laptop. How large is the
csv file and how much RAM do you have?

Also it helps to post the whole code you are trying to run. I don't
care much for guesswork.
