Hmm, that's annoying. I don't directly understand why this is failing, though (but I can reproduce it by setting `sys.modules['pyarrow'] = None` first and then important pandas locally). In pandas, in cython code, we essentially do [this](https://github.com/pandas-dev/pandas/blob/b00d4f6710ff6c1c80319196657c31c2cf6c70ff/pandas/_libs/lib.pyx#L130-L137): ``` cdef bint PYARROW_INSTALLED = False try: import pyarrow as pa PYARROW_INSTALLED = True except ImportError: pa = None ``` Trying to import pyarrow after `sys.modules['pyarrow'] = None` does raise a `ModuleNotFoundError`, which is a subclass of `ImportError`, and so I think should be correctly caught by the block above? Unless that code does not behave exactly as expected when in cython. -- This is an automated message from the Apache Git Service.
