inference_prune.py比inference.py显存多

[wuzuowuyou]

inference_prune.py比inference.py显存多？多出400多M，这是为啥呢？

[wuzuowuyou]

prune之后和原本的比较，显存没有减少，这是为啥呢？

[csliuchang]

大哥为啥我的inference没有编译成功，可以请教一下吗

[wuzuowuyou]

贴上错误啊

我用的python3.6

[wuzuowuyou]

你这个是编译那个c++库不对啊，环境配置不对，改makefile

这个https://github.com/BADBADBADBOY/pse-lite.pytorch/blob/master/pse/include/pybind11/detail/common.h 112-114行改成3.6

[csliuchang]

对的，改完之后少了一个bug，但是好像还是要重写makefile，不太会cpp编译。。。

改完还不能编译成功？贴报错

你装opencv了吗，要3.0+

[wuzuowuyou]

给你贴一个我修改好的makfile，供你参考

CXXFLAGS = -I include  -std=c++11 -O3

DEPS = lanms.h $(shell find include -xtype f)
CXX_SOURCES = adaptor.cpp include/clipper/clipper.cpp
#OPENCV = `pkg-config --cflags --libs opencv`

INCLUDES = -I/data_1/Yang/software_install/Anaconda1105/envs/libtorch1.0/include
LIBDIRS = -L/data_1/Yang/software_install/Anaconda1105/envs/libtorch1.0/lib
LIBS = -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml

LIB_SO = adaptor.so

$(LIB_SO): $(CXX_SOURCES) $(DEPS)
	$(CXX) -o $@ $(CXXFLAGS) $(LDFLAGS) $(CXX_SOURCES) --shared -fPIC $(INCLUDES) $(LIBDIRS) $(LIBS)

clean:
	rm -rf $(LIB_SO)

[csliuchang]

应该是未配置c++版本的opencv，相关目录里面没有opencv文件

[wuzuowuyou]

你们能测一下显存吗？我这里剪枝之后显存反而比之前多了，模型大小和参数量确实是减少了

确实显存更大，我测试了，模型初始化的时候，确实是压缩的模型使用的显存更少一些，说明权重确实减少了，但是在模型forward的时候，同样大小的图片，反而是权重小的模型占用的显存更大，导致整体显存大于压缩后模型显存，我也很莫名其妙
