· in python shape [0] returns the dimension but in this code it is returning total number of set. · 82 yourarray. shape or np. shape() or np. ma. shape() returns the shape of your ndarray as a tuple; · shape is a tuple that gives you an indication of the number of dimensions in the array. · theres one good reason why to use shape in interactive work, instead of len (df): M_train = train_set_x_orig. shape [0] Please can someone tell me work of shape [0] and shape [1]? (r,) and (r,1) just add (useless) parentheses but still express respectively 1d and 2d array shapes, parentheses around a tuple force the evaluation order and prevent it to be read as a list of values (e. g. Pandas dataframe valueerror: · the python attributeerror: Nonetype object has no attribute shape occurs after passing an incorrect path to cv2. imread () because the path of image/video file is wrong or the name of image/video you passed is incorrect. With shape i can see that just by adding. shape after my filtering. A placeholder does not hold state and merely defines the type and shape of the data to flow. · how do i get a size of a pictures sides with pil or any other python library? Trying out different filtering, i often need to know how many items remain. Shape n, expresses the shape of a 1d array with n items, and n, 1 the shape of a n-row x 1-column array. In function calls). With len () the editing of the command-line becomes much more cumbersome, going back and forth. Objects cannot be broadcast to a single shape it computes the first two (i am running several thousand of these tests in a loop) and then dies. So in your case, since the index value of y. shape[0] is 0, your are working along the first dimension of your array. And you can get the (number of) dimensions of your array using yourarray. ndim or np. ndim(). Shape of passed values is (x, ), indices imply (x, y) asked 11 years, modified 7 years, viewed 60k times It gives the n of the ndarray since all arrays in numpy are just n-dimensional arrays (shortly called as ndarray s)) You can think of a placeholder in tensorflow as an operation specifying the shape and type of data that will be fed into the graph. placeholder x defines that an unspecified number of rows of shape (128, 128, 3) of type float32 will be fed into the graph.
