Convert a NumPy array to a PyTorch tensor and vice versa

WebSep 6, 2024 · The variable to predict (often called the class or the label) is politics type, which has possible values of conservative, moderate or liberal. For PyTorch multi-class classification you must encode the variable to predict using ordinal encoding. The demo sets conservative = 0, moderate = 1 and liberal = 2. The order of the encoding is arbitrary. WebTorch defines 10 tensor types with CPU and GPU variants which are as follows: [ 1] Sometimes referred to as binary16: uses 1 sign, 5 exponent, and 10 significand bits. Useful when precision is important at the expense of range. [ 2] Sometimes referred to as Brain Floating Point: uses 1 sign, 8 exponent, and 7 significand bits.
