SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats #557

The error message comes from

File "/home/xxxx/mambaforge/lib/python3.10/site-packages/segyio/trace.py", line 290, in setitem self.filehandle.puttr(self.wrapindex(i), xs) SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats

The following is further explained in https://docs.python.org/3/c-api/arg.html#strings-and-buffers " Note For all # variants of formats (s#, y#, etc.), the macro PY_SSIZE_T_CLEAN must be defined before including Python.h. On Python 3.9 and older, the type of the length argument is Py_ssize_t if the PY_SSIZE_T_CLEAN macro is defined, or int otherwise. "

I ran into a similar problem with segyio ver. 1.9.3. Reinstalling the segyio with the latest version (1.9.12) resolved the issue.
