"Mars tensor is the counterpart of Numpy :class:`numpy.ndarray` and "
"implements a subset of the Numpy ndarray interface. It tiles a large "
"tensor into small chunks and describe the inner computation with a "
"directed graph. This lets us compute on tensors larger than memory and "
"take advantage of the ability of multi-cores or distributed clusters."
msgstr ""
"Mars tensor 对应 Numpy ndarray，实现了 Numpy ndarray 接口的子集。在执行中"
"，Mars tensor 将一个大张量切分成很多小块，并用有向图描述块之间的计算。"
"这使我们可以在大于内存的张量上进行计算，并利用多核或分布式集群的能力。"
