เวลาเจอ error ว่า Segmentation fault โดยไม่มีคำอธิบายใดๆ จะไปไม่เป็น
เลยจะให้พ่น error ออกมาด้วย Python faulthandler module
First add the following to the top of your module.
import faulthandler; faulthandler.enable()
Then re-run your program with the faulthandler startup flag.
# pass as an argument python -Xfaulthandler test.py # Or as an environment variable. PYTHONFAULTHANDLER=1 python test.py
ก็จะได้ประมาณนี้
$ /usr/local/bin/python3.7 -Xfaulthandler test.py Fatal Python error: Segmentation fault Current thread 0x00007fc9540b6740 (most recent call first): File "/home/jack/.local/lib/python3.7/site-packages/pandas/core/internals/managers.py", line 261 in items File "/home/jack/.local/lib/python3.7/site-packages/pandas/core/internals/managers.py", line 310 in __len__ File "/home/jack/.local/lib/python3.7/site-packages/pandas/core/series.py", line 599 in __len__ File "/home/jack/.local/lib/python3.7/site-packages/pandas/io/json/_json.py", line 962 in _try_convert_data File "/home/jack/.local/lib/python3.7/site-packages/pandas/io/json/_json.py", line 1172 in <lambda> File "/home/jack/.local/lib/python3.7/site-packages/pandas/io/json/_json.py", line 1152 in _process_converter File "/home/jack/.local/lib/python3.7/site-packages/pandas/io/json/_json.py", line 1172 in _try_convert_types File "/home/jack/.local/lib/python3.7/site-packages/pandas/io/json/_json.py", line 892 in parse File "/home/jack/.local/lib/python3.7/site-packages/pandas/io/json/_json.py", line 777 in _get_object_parser File "/home/jack/.local/lib/python3.7/site-packages/pandas/io/json/_json.py", line 755 in read File "/home/jack/.local/lib/python3.7/site-packages/pandas/io/json/_json.py", line 618 in read_json File "/home/jack/.local/lib/python3.7/site-packages/pandas/util/_decorators.py", line 296 in wrapper File "/home/jack/.local/lib/python3.7/site-packages/pandas/util/_decorators.py", line 199 in wrapper File "test.py", line 4 in <module> Segmentation fault
