Hi, I have a test.exe, and also have a test-gdb.py. The test-gdb.py is a pretty printer associated with test.exe. The expect way is that when GDB load the test.exe, the test-gdb.py is also loaded. This is called: Debugging with GDB: Python Auto-loading (https://sourceware.org/gdb/onlinedocs/gdb/Python-Auto_002dloading.html#Python-Auto_002dloading)
Now, I have correctly set the auto loading option in a user custom .gdb file which is E:\code\gdb\mybuild\bin\my.gdb
...
set auto-load safe-path /
set auto-load python-scripts on
But I found an issue that the custom my.gdb is executed AFTER gdb loading the exe file, so this pretty printer is not loaded. See the debugger plugin log:

A possible fix is that firstly start gdb.exe, and run my.gdb, and finally load the test.exe.
BTW: I'm going to test the auto load python pretty printer associated with DLL file, I think it don't have this issue, because DLL files are loaded later after running the exe file.
EDIT: Yes, confirmed, no issue with python pretty printer auto load with DLL.
OK, problem solved, I just add those command in the Debugger initial argument (in debugger plugin setting dialog)
-iex "set auto-load safe-path /"
