`pyarrow` (version `0.10.0`) appears to crash sporadically with a segmentation fault when reading parquet files if it is used in a program where `torch` is imported first.
A self-contained example is available here: https://gitlab.com/ostrokach/pyarrow_pytorch_segfault. Basically, running ```bash python -X faulthandler -c "import torch; import pyarrow.parquet as pq; _ = pq.ParquetFile('example.parquet').read_row_group(0)" ``` sooner or later results in a segfault: ```python-traceback Fatal Python error: Segmentation fault Current thread 0x00007f52959bb740 (most recent call first): File "/home/kimlab1/strokach/anaconda/lib/python3.6/site-packages/pyarrow/parquet.py", line 125 in read_row_group File "<string>", line 1 in <module> ./test_fail.sh: line 5: 42612 Segmentation fault (core dumped) python -X faulthandler -c "import torch; import pyarrow.parquet as pq; _ = pq.ParquetFile('example.parquet').read_row_group(0)" ``` The number of iterations before a segfault varies, but it usually happens within the first several calls. Running ```bash python -X faulthandler -c "import pyarrow.parquet as pq; import torch; _ = pq.ParquetFile('example.parquet').read_row_group(0)" ``` works without a problem.
