本文简要介绍 python 语言中 numpy.logical_and 的用法。 用法: numpy.logical_and(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True [, signature, extobj ]) = <ufunc 'logical_and'>逐元素计算 x1 AND x2 的真值。
logical_and(torch.tensor([True, False, True]), torch.tensor([True, False, False])) tensor([ True, False, False]) >>> a = torch.tensor([0, 1, 10, 0], dtype=torch.int8) >>> b = torch.tensor([4, 0, 1, 0], dtype=torch.int8) >>> torch.logical_and(a, b) tensor([...
SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. The following command will help you install SymPy − SymPy是用于符号数学的Python...
In this blog, we will cover 3 logical operators in Python: AND, OR, and NOT. Python logical operators are used to evaluate the values to be either true or false. These are primarily used for evaluating logical operators with two or more conditions. ...
