[英]What is the dask equivalent of numpy.tile?
Dask ( http://dask.pydata.org/en/latest/array-api.html ) is a flexible parallel computing library for analytics. Dask( http://dask.pydata.org/en/latest/array-api.html )是一个灵活的分析计算库。 It scales to big data, in constrast to Numpy and has many similar methods. 它可以扩展到大数据,与Numpy相比,并且有许多类似的方法。 How can I achieve the same effect as numpy.tile
on a dask array? 如何在dask数组上实现与numpy.tile
相同的效果?
Using dask.array.concatenate()
could be a possible workaround. 使用dask.array.concatenate()
可能是一种可能的解决方法。
Demo in NumPy: NumPy演示:
In [374]: x = numpy.arange(4).reshape((2, 2))
In [375]: x
Out[375]:
array([[0, 1],
[2, 3]])
In [376]: n = 3
In [377]: numpy.tile(x, n)
Out[377]:
array([[0, 1, 0, 1, 0, 1],
[2, 3, 2, 3, 2, 3]])
In [378]: numpy.concatenate([x for i in range(n)], axis=1)
Out[378]:
array([[0, 1, 0, 1, 0, 1],
[2, 3, 2, 3, 2, 3]])
