the PCA input X shape should be (n, d) rather than (d, n)

[xiuliren]

the documentation said that the input of PCA should have shape of (d,n), but actually I have to use array with a shape of (n,d).

Yes you can if you transpose your input matrix.

sorry, the shape should be (d,n), the documentation is correct.
