WebPython float uses 8 bytes (or 64 bits) to represent real numbers. Unlike the integer type, the float type uses a fixed number of bytes. Technically, Python uses 64 bits as follows: 1 bit for sign (positive or negative) 11 bits for exponent 1.5e-5 1.5 x 10 -5 (exponent is -5) the range is [-1022, 1023]. 52 bits for significant digits WebTo use the Estimator API to develop a training script, perform the following steps.

Web1 Step 1 : Get the dtype of the tensor. This will tell you about the number of bytes e.g.float64 is 64 bits = 8 Bytes. Step 2 Get the shape of the Tensor. This will give you the number of place-holders of the dtype. lets's assume shape = m x n x p Count of the placeholders is C = m * n * p Memory = 8 * C => Memory = 8 *m * n * p Bytes.
