mindspore.ops.functional ============================= functional算子是经过初始化后的Primitive，可以直接作为函数使用。functional算子的使用示例如下： .. code-block:: python from mindspore import Tensor, ops from mindspore import dtype as mstype input_x = Tensor(-1, mstype.int32) input_dict = {'x':1, 'y':2} result_abs = ops.absolute(input_x) print(result_abs) result_in_dict = ops.in_dict('x', input_dict) print(result_in_dict) result_not_in_dict = ops.not_in_dict('x', input_dict) print(result_not_in_dict) result_isconstant = ops.isconstant(input_x) print(result_isconstant) result_typeof = ops.typeof(input_x) print(result_typeof) # outputs: # 1 # True # False # True # Tensor[Int32] 神经网络层函数 ---------------- 神经网络 ^^^^^^^^ .. mscnplatformautosummary:: :toctree: ops :nosignatures: :template: classtemplate.rst mindspore.ops.adaptive_avg_pool2d mindspore.ops.avg_pool2d mindspore.ops.ctc_greedy_decoder mindspore.ops.deformable_conv2d mindspore.ops.dropout2d mindspore.ops.dropout3d mindspore.ops.flatten mindspore.ops.interpolate mindspore.ops.kl_div mindspore.ops.lrn mindspore.ops.max_pool3d mindspore.ops.pad mindspore.ops.padding 损失函数 ^^^^^^^^^^ .. mscnplatformautosummary:: :toctree: ops :nosignatures: :template: classtemplate.rst mindspore.ops.cross_entropy mindspore.ops.nll_loss mindspore.ops.smooth_l1_loss 激活函数 ^^^^^^^^^^ .. mscnplatformautosummary:: :toctree: ops :nosignatures: :template: classtemplate.rst mindspore.ops.fast_gelu mindspore.ops.gumbel_softmax mindspore.ops.hardshrink mindspore.ops.hardswish mindspore.ops.log_softmax mindspore.ops.mish mindspore.ops.selu mindspore.ops.soft_shrink mindspore.ops.softsign mindspore.ops.tanh 采样函数 ^^^^^^^^^^ .. mscnplatformautosummary:: :toctree: ops :nosignatures: :template: classtemplate.rst mindspore.ops.grid_sample 数学运算函数 ---------------- 逐元素运算 ^^^^^^^^^^^^^ .. mscnplatformautosummary:: :toctree: ops :nosignatures: :template: classtemplate.rst mindspore.ops.abs mindspore.ops.acos mindspore.ops.acosh mindspore.ops.add mindspore.ops.addn mindspore.ops.asin mindspore.ops.asinh mindspore.ops.atan mindspore.ops.atan2 mindspore.ops.atanh mindspore.ops.bernoulli mindspore.ops.bessel_i0 mindspore.ops.bessel_i0e mindspore.ops.bessel_i1 mindspore.ops.bessel_i1e mindspore.ops.bessel_j0 mindspore.ops.bessel_j1 mindspore.ops.bessel_k0 mindspore.ops.bessel_k0e mindspore.ops.bessel_k1 mindspore.ops.bessel_k1e mindspore.ops.bessel_y0 mindspore.ops.bessel_y1 mindspore.ops.bitwise_and mindspore.ops.bitwise_or mindspore.ops.bitwise_xor mindspore.ops.ceil mindspore.ops.cos mindspore.ops.cosh mindspore.ops.div mindspore.ops.erf mindspore.ops.erfc mindspore.ops.exp mindspore.ops.expm1 mindspore.ops.floor mindspore.ops.floor_div mindspore.ops.floor_mod mindspore.ops.inplace_add mindspore.ops.inplace_sub mindspore.ops.inplace_update mindspore.ops.inv mindspore.ops.invert mindspore.ops.lerp mindspore.ops.log mindspore.ops.log1p mindspore.ops.logical_and mindspore.ops.logical_not mindspore.ops.logical_or mindspore.ops.mul mindspore.ops.neg mindspore.ops.pow mindspore.ops.round mindspore.ops.sin mindspore.ops.sinh mindspore.ops.sub mindspore.ops.tan mindspore.ops.trunc mindspore.ops.truncate_div mindspore.ops.truncate_mod mindspore.ops.xlogy .. list-table:: :widths: 50 50 :header-rows: 1 * - functional - Description * - mindspore.ops.absolute - `absolute` will be deprecated in the future.
