chunkedarraybase.jl's Issues

ERROR: DivideError: integer division error

The case where ncvar.chunksize = (0,0,0) returns an error.

Just for reference, if someone wants to further develop the ideas proposed here.

Thanks for the prototype!

MWE

import NetCDF
using ChunkedArrayBase

# Function def
ChunkedArrayBase.eachchunk(a::NetCDF.NcVar) = ChunkedArrayBase.GridChunks(a, map(Int64,a.chunksize))

# DATA
url = "https://www.unidata.ucar.edu/software/netcdf/examples/ECMWF_ERA-40_subset.nc"
download(url, "ECMWF_ERA-40_subset.nc")

ds = NetCDF.open("ECMWF_ERA-40_subset.nc")
ncvar = ds["tp"]

eachchunk(ncvar)
