Installation error

[ekazakos]

Hi,

I follow the instructions and my installation fails. You can find my error log in: install_log.txt. Linker complains that there are multiple definitions of the same thing in different files. Upon checking flash-attention/csrc/flash_attn_rocm/src/, I found out that for many files there are two files with identical content and only different names, e.g. device_memory.hip and device_memory_hip.hip, which were created due to two object files being created (device_memory.o and device_memory_hip.o).

Any help would be appreciated.

@ekazakos, Can you try to delete both device_memory.hip and device_memory_hip.hip, and run python setup.py clean? Then run pip install . with the original device_memory.cpp.

Hi, facing a similar issue, after the patch the header files are not generated for the composable kernel, but the code hipifies the .cpp with hipified header requirements. Precisely speaking, the device_memory.hpp requirement is transformed into device_memory_hip.hpp, but due to the patch, we are skipping the creation of these header files
