Could send me a small test program that triggers the bug?

I'll try looking at it and sending it upstream.

Thanks,
Diane

Hello Diane,
The exact message is:

args2 = [_get_recursive(dsk, k, cache) for k in args]
  File "/usr/lib/python3/dist-packages/dask/core.py", line 136, in <listcomp>
    args2 = [_get_recursive(dsk, k, cache) for k in args]
  File "/usr/lib/python3/dist-packages/dask/core.py", line 132, in _get_recursive
    res = cache[x] = _get_recursive(dsk, dsk[x], cache)
  File "/usr/lib/python3/dist-packages/dask/core.py", line 128, in _get_recursive
    hashable = ishashable(x)
  File "/usr/lib/python3/dist-packages/dask/core.py", line 20, in ishashable
    hash(x)
RecursionError: maximum recursion depth exceeded while calling a Python object

I have used the
for i in listIndex:
    daskdataframe.loc[i].values.compute()

The daskdataframe is from a read_csv and the csv has 2.5 Gb Volume.

This seems relevant:

Hi,

Now that there's a new version of dask, which includes upstream's
fixes, is there any chance this problem got resolved?

Thanks,
