The L1 norm is a measure of distance or magnitude in vector spaces. For a matrix, the L1 norm is calculated as the sum of the absolute values of its elements. importnumpyasnp# create a matrixmatrix1 = np.array([[1,2,3], [4,5,6], ...

输入一个张量t,把t中的每一个元素的值都压缩在clip_value_min和clip_value_max之间。小于min的让它等于min,大于max的元素的值等于max。
ctx是结构体OpContext定 义的对象, requested是OPContext结构体下的函数: // brief Resources requested by the operator std::vector<Resource> requested; // 用来返回操作所需的资源. ctx.requested返回的是一个向量容器, ctx.requested[batchnorm::kTempSpace]即ctx.requested[0]返回一个Resource对象, 然后 ...
