可以确认下 ${path_to_TNN}/source/tnn/device/opencl/cl 下是否正常生成 opencl_program.cc，以及link TNN lib的时候是否有包含对应的目标文件

没有生成opencl_program.cc，也没有对应的目标文件libtnn_wrapper.so。应该怎么处理呢？

在{path_to_tnn}/source/tnn/device/opencl下手动执行python ./cl/opencl_codegen.py ./cl/

@lnmdlong 谢谢！可以成功编译了

lao-wang123 commented 2 years ago

碰见这个问题了，折腾一天，一个老哥的方法是把CMakeLists 里面的set(TNN_OPENCL_ENABLE OFF CACHE BOOL "" FORCE) 设置成OFF后就可以正常跑通了

lao-wang123 commented 2 years ago

我发现我在{path_to_tnn}/source/tnn/device/opencl下手动执行python ./cl/opencl_codegen.py ./cl/后生成了opencl_program.cc，但是仍然没有libtnn_wrapper.so文件。如果修改cmakelist.txt会导致很多功能用不了，我想知道这个问题的原因是什么
