I naively tried to do dd.merge(a, b, on="column_with_ten_values"), where a and b were both large DataFrames with thousands of partitions each.

Eventually the compute failed with:

[File /opt/conda/envs/coiled/lib/python3.9/site-packages/dask/dataframe/multi.py:275, in merge_chunk()

Hi!

This line requires the length of bands to be even:

https://github.com/scipy/scipy/blob/b5d8bab88af61d61de09641243848df63380a67f/scipy/signal/_fir_filter_design.py#L982

But from the docs, and the example that uses a flattened sequence as bands (see below), it's not that obvious that firls requires an even number of edges. Could this be improved/clarified in the docs? Thank you!

Seems args are different

Additional Information

dtype argument added in NumPy version 1.20.

Description of the desired feature

The spacing parameter of the rolling_window function controls the distance between the center of two adjacent windows.
Nevertheless, the docstring reads:

    spacing : float, tuple = (s_north, s_east), or None
        The window size in the South-North and West-East directions,
        respectively. A single value means that the size is equal
