da.zeros_like instanciated arrays are not writeable when map_blocks is run over them Summary Dask arrays created with da.zeros_like are not writeable when used alongside with map_blocks. Trying to write in-place the received block array inside of the mapped function will produce the following error…

All input data of dask functions must be treated at all times as strictly immutable, no ifs, no buts. When immutability is not enforceable (e.g. a list or dict input parameter) and you do modify your input, things will go horribly wrong if you need to re-run your task at a later time or if the same…
