Thank you. I used the following steps to repro (on ubuntu 14) : 1. conda section to setup the python environment https://github.com/apache/arrow/blob/master/docs/source/python/development.rst <https://github.com/apache/arrow/blob/master/docs/source/python/development.rst> 2. Build python gandiva tests python setup.py build_ext --build-type=$ARROW_BUILD_TYPE --with-gandiva —inplace 3. Run python gandiva tests pytest pyarrow --only-gandiva The test silently dies without printing any error msg. So, I modified test_gandiva.py to use pdb and stepped through till I got the error (pdb.set_trace() in test_tree_expr_builder()).
