I was recently trying to open a csv dataset, and when I got to the 41% complete point, a window opened and said that I was out of memory. How would I solve this problem? I'm trying to get this cvs file into a .dat type format for future use in a shazam project. If I can't solve this problem directly, is there any other way of doing this? The dataset has over 800,000 observations and 140 variables.
