Alexey Strokach updated ARROW-3346:
-----------------------------------
Description:
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
{{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:
{{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
{{python -X faulthandler -c "import pyarrow.parquet as pq import torch; _ =
pq.ParquetFile('example.parquet').read_row_group(0)"}}
works without a problem.
