hi... I am using principal component analysis for dimensionality reduction in python. am having this following error... >>> import numpy as np >>> import matplotlib.pyplot as plt >>> import mlpy >>> np.random.seed(0) >>> mean,cov,n=[0,0],[[1,1],[1,1.5]],100 >>> x=np.random.multivariate_normal(mean,cov,n) >>> pca.learn(x) Traceback (most recent call last): File "<interactive input>", line 1, in <module> NameError: name 'pca' is not defined >>> would you please help me in finding the error...? what was my fault? how could i use PCA in python..?
