创建Session完毕后,需要使用sess.run(op)方法来执行你想要的操作 # 启动默认图. sess = tf.Session() # 调用 sess 的 'run()' 方法来执行矩阵乘法 op, 传入 'product' 作为该方法的参数. # 上面提到, 'product' 代表了矩阵乘法 op 的输出, 传入它是向方法表明, 我们希望取回 # 矩阵乘法 op 的输出. ...

从⼆维张量(矩阵)的⾓度看,张量的卷积运算是对dot product和cross运算的⼀种推⼴,对两个矩阵的形状没有那么严格的要求,可以试想两个平⾯运算,两个⽅块运算。4、numpy.pad填充函数:看这篇博客,写的很详细,有案例,5、张量中的切⽚操作:x1=np.random.rand(3,4,5)x2 =x1[:,2,:]:...
需要注意的是,乘积操作product并没有为Tensor实现,因为这些操作通常会生成具有更大陪域的布局,可能会超出Tensor的数据范围。 Slicing a Tensor (切片) 通过坐标访问tensor会返回tensor中的一个元素,而对tensor进行切片访问则会返回切片中所有的元素对应的子tensor。
