"size changed, may indicate binary incompatibility"

See original GitHub issue

What is that and how do I silence this warning?

Update: I managed to reproduce locally… but only with manylinux1, not manylinux2010!

Here is a manylinux1-produced wheel:

Python 3.7.3 (default, Apr  3 2019, 19:16:38) 
[GCC 8.0.1 20180414 (experimental) [trunk revision 259383]] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyarrow as pa
>>> pa.lib.DictionaryMemo.__basicsize__
160

Here is a manylinux2010-produced wheel:

Python 3.7.3 (default, Apr  3 2019, 19:16:38) 
[GCC 8.0.1 20180414 (experimental) [trunk revision 259383]] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyarrow as pa
>>> pa.lib.DictionaryMemo.__basicsize__
184
