Streaming broken for Pile

I am trying to access monology/pile-uncopyrighted via streaming with the lines:
pile = load_dataset("monology/pile-uncopyrighted", split="validation", streaming=True)
for sample in pile:
print(sample)
However I get the following difficult to parse error when beginning the loop:

Is this expected? Please advise.
Have you installed the zstandard python package ?
No I did not. Installing zstandard seems to produce the expected behavior. Perhaps this solution should be hinted at in the above error message, if possible.
I installed zstandard but still cannot stream. Has anyone figured this out?
EDIT: Install zstandard before importing the transformers library. If you load the dataset before pip installing zstandard you must restart the kernel and try again.
