Many tests failed at the same time in this package.

• I will close this issue when there are no more failures in this package and
  there is at least one pass.
• No new issues will be filed for this package until this issue is closed.
• If there are already issues for individual test cases, I will close them when
  the corresponding test passes. You can close them earlier, if you prefer, and
  I won't reopen them while this issue is still open.

Here are the tests that failed:

• test_series_from_arrow[expected0-pyarrow_array0]
• test_series_from_arrow[expected1-pyarrow_array1]
