Error in Naive Bayes Classification section

[robertjankowski]

While learning about Naive Bayes Classification I encountered a problem with bayespost function. When I rewrited this function in my jupyter notebook I got following error

AssertionError: Argument data must have NDArray type, but got ...

I wanted to fix this and change two lines in this function

def bayespost(data):
    logpost = logpy.copy()
    logpost += (logpx * x + logpxneg * (1 - x)).sum(0)
    logpost -= nd.max(logpost)
    post = nd.exp(logpost)  # before was:  post = nd.exp(logpost).asnumpy()
    post /= nd.sum(post)
    return post.asnumpy() # before was:  post

I am also curious if only I got this error
