error of unhashable type

Doing this

(pyreq/require-python 'sklearn.datasets)
(def newsgroups (sklearn.datasets/fetch_20newsgroups :subset "all" :remove (builtins/tuple [ "headers" "footers" "quotes"])))

and teh opening newsgroups i te ccider-inspector gives an error
Seems to happen only in cider-inspector ...

從 issue 中的重現開始，沿著回報的 stack 追蹤 libpython_clj2/python/base.clj 第 180 行、bridge_as_jvm.clj 第 231 行，以及 orchard/inspect.clj 第 658-660 行和第 792 行。確定為什麼檢查傳回的物件會對 numpy.ndarray 進行雜湊，然後驗證 cider-inspector 能夠在沒有 TypeError 的情況下呈現該值。
