1.5. 获取Tensor数据 要从Tensor中提取数据并保存到文件中或传递给其他函数，可以使用data_ptr函数。对于单个元素的Tensor，使用item函数可获取具体数值。1.6. 数据类型与设备类型 Libtorch支持多种数据类型，包括float16, float32, float64, int8, int16, int32, uint8等，并提供to函数进行类型转换...
Tensor可以具有任意维数,并且可以包含不同类型的数据,如整数、浮点数等。 创建Tensor时,可以使用以下方法指定数据类型: 1. 使用默认的数据类型:在创建Tensor时,如果不指定数据类型,将使用默认的数据类型(通常是float)。例如,创建一个空的3x3的Tensor: ```cpp torch::Tensor tensor = torch::empty(3, 3); ```...
