To apply pca for a large csv

[Rahul Gupta]

Hello all, i have a csv of 1 gb which consists of 25000 columns and 20000 rows. I want to apply pca so i have seen sciki-learn had inbuilt fucntionality to use that. But i have seen to do eo you have to load data in data frame. But my machine is i5 with 8 gb of ram which fails to load all this data in data frame and shows memory error. Is there any alternative way that still i could aaply PCA on the same machine to the same rata set
