将延迟对象列表转换为Dask数组

我有一个使用

dask时获得的
Delayed
对象列表。persist

这些结果是一个浮点列表，我想做的是创建一个dask数组。接下来该怎么办？我知道存在，但我是否应该迭代列表中的所有

Delayed

对象并连接数组？如果能在这方面得到任何帮助，我将不胜感激

在再次阅读文档，特别是本节之后，我找到了如何做

我刚刚修改了延迟函数，以返回一个

np.array

，而不是

列表

，并且能够实现文档中所示的功能

我将

延迟

转换为

Dask数组

的代码如下所示：

sample = stacked_features[0].compute()
dim = (len(stacked_features), len(sample))
stacked_features = [
    dask.array.from_delayed(lazy, dtype=float, shape=sample.shape)
    for lazy in stacked_features
]
stacked_features = (
    dask.array.stack(stacked_features, axis=0).reshape(dim).rechunk(dim)
)
