ml-andrewng-python's Issues

a probelm in name the colums

I found an error in ex1, after loading ex2data in line s= vstack
please i sugust you to
replace it with other name so that 0-d array error solves. as size is predefined it returns the size of the array which makes vstack an error
thankyou.

TypeError : iteration over 0-d array

Line number 123 , the usage of size

s = np.array(data.size)

Returns the number of the elements whereas only the elements of column 'size' are required .

It is giving the error - TypeError : iteration over 0-d array

So it is better to change the argument name on line number 122 to anything other than size.

data = pd.read_csv("ex1data2.txt",names=["size","bedrooms","price"])
