问题 Hi i tried to write a code, where i write a number on the screen with pygame and then a neural Network predicts the number i wrote. My problem is that i trained my neural network with image arrays in a (28, 28, 3). So i tried to reshape my (280, 280, 3) array. but when i do so my array is None. I use Python 3.7 string_image = pygame.image.tostring(screen, 'RGB') temp_surf = pygame.image.fromstring(string_image, (280, 280), 'RGB') array = pygame.surfarray.array3d(temp_surf) array = array

I'm trying to import a CSV into MySQL using odo but am getting a datashape error. My understanding is that datashape takes the format: var * { column: type ... } where var means a variable number of rows. I'm getting the following error: AssertionError: datashape must be Record type, got 0 * { tod: ?string, interval: ?string, iops: float64, mb_per_sec: float64 } I'm not sure where that 0 number of rows is coming from. I've tried explicitly setting the datashape using dshape() , but continue to get the same error. Here's a stripped down version of the code that recreates the error: from odo
