+Subject: [PATCH] test: import arro3 and nanoarrow lazily in
+ test_scalar_conversion
+
+Upstream-Status: Inappropriate [nanoarrow publishes no riscv64 wheel]
+
+python/tests/test_expr.py imports arro3.core and nanoarrow at module
+scope, but the only test using either is test_scalar_conversion. nanoarrow
+is a separate compiled project with no riscv64 wheel on PyPI or on
+pypi.riseproject.dev, so that module-scope import makes the whole file --
+roughly 185 other tests -- fail to collect on riscv64.
+
+Move both imports into the one test that needs them, using
+pytest.importorskip, the mechanism the suite already uses for pandas,
+polars and pyarrow.cffi in test_context.py and test_dataframe.py. The
+rest of the file then runs, and test_scalar_conversion skips instead of
+erroring. The pyarrow and __arrow_c_array__ assertions it also carries
+are covered by the pyarrow-only paths elsewhere in the file.
