numpy.add.reduce的用法

本文详细介绍了如何使用NumPy的add.reduce方法对不同维度的矩阵进行加法累加操作,展示了对于不同轴参数设置下,该方法的运行结果,并对比了其与sum方法的相似之处。
>>> X = np.arange(8).reshape((2,2,2))
>>> X
array([[[0, 1],
        [2, 3]],
       [[4, 5],
        [6, 7]]])
>>> np.add.reduce(X, 0)
array([[ 4,  6],
       [ 8, 10]])
>>> np.add.reduce(X) # confirm: default axis value is 0
array([[ 4,  6],
       [ 8, 10]])
>>> np.add.reduce(X, 1)
array([[ 2,  4],
       [10, 12]])
>>> np.add.reduce(X, 2)
array([[ 1,  5],
       [ 9, 13]])

此用法和sum类似,只是该方法只是适用于小型的矩阵方法

为什么: Weights only load failed. This file can still be loaded, to do so you have two options, do those steps only if you trust the source of the checkpoint. (1) In PyTorch 2.6, we changed the default value of the `weights_only` argument in `torch.load` from `False` to `True`. Re-running `torch.load` with `weights_only` set to `False` will likely succeed, but it can result in arbitrary code execution. Do it only if you got the file from a trusted source. (2) Alternatively, to load with `weights_only=True` please check the recommended steps in the following error message. WeightsUnpickler error: Unsupported global: GLOBAL numpy._core.multiarray.scalar was not an allowed global by default. Please use `torch.serialization.add_safe_globals([numpy._core.multiarray.scalar])` or the `torch.serialization.safe_globals([numpy._core.multiarray.scalar])` context manager to allowlist this global if you trust this class/function. Check the documentation of torch.load to learn more about types accepted by default with weights_only https://pytorch.org/docs/stable/generated/torch.load.html. _pickle.UnpicklingError: Unsupported global: GLOBAL numpy._core.multiarray.scalar was not an allowed global by default. Please use `torch.serialization.add_safe_globals([numpy._core.multiarray.scalar])` or the `torch.serialization.safe_globals([numpy._core.multiarray.scalar])` context manager to allowlist this global if you trust this class/function.
