一、lanms无法编译的错误：
错误所示：
RuntimeError: Cannot compile lanms: /home/zhengyujie/EAST-master/lanms
网上查过很多方法都没有解决这个问题，所以我将eval.py文件中第100行的boxes = lanms.merge_quadrangle_n9(boxes.astype('float32'), nms_thres)
换成了boxes = nms_locality.nms_locality(boxes.astype(np.float64), nms_thres)，然后注释掉了import lanms。
另一种方法，就是修改Makefile文件：
CXXFLAGS = -I include -std=c++11 -O3 $(shell python3-config --cflags)
LDFLAGS = $(shell python3-config --ldflags)
DEPS = lanms.h $(shell find include -xtype f)
CXX_SOURCES = adaptor.cpp include/clipper/clipper.cpp
LIB_SO = adaptor.so
$(LIB_SO): $(CXX_SOURCES) $(DEPS)
$(CXX) -o $@ $(CXXFLAGS) $(LDFLAGS) $(CXX_SOURCES) --shared -fPIC
clean:
rm -rf $(LIB_SO)
改为：
CXXFLAGS = -I include -std=c++11 -O3 -I/home/XXX/anaconda3/include/python3.6m/
LDFLAGS = $(shell python3-config --ldflags)
DEPS = lanms.h $(shell find include -xtype f)
CXX_SOURCES = adaptor.cpp include/clipper/clipper.cpp
LIB_SO = adaptor.so
$(LIB_SO): $(CXX_SOURCES) $(DEPS)
$(CXX) -o $@ $(CXXFLAGS) $(LDFLAGS) $(CXX_SOURCES) --shared -fPIC
clean:
rm -rf $(LIB_SO)
二、调用测试代码显示0 images：
直接都换成换成绝对路径
python eval.py --test_data_path=/home/XXX/EAST-master/tmp/ch4_test_images/ --gpu_list=0 --checkpoint_path=/home/XXX/EAST/master/tmp/east_icdar2015_resnet_v1_50_rbox/ --output_dir=/home/XXX/EAST-master/tmp/tested_images/
三、
/home/XXX/EAST-master/icdar.py:250: RuntimeWarning: invalid value encountered in float_scalars
return np.linalg.norm(np.cross(p2 - p1, p1 - p3)) / np.linalg.norm(p2 - p1)
/home/XXX/EAST-master/icdar.py:250: RuntimeWarning: invalid value encountered in float_scalars
return np.linalg.norm(np.cross(p2 - p1, p1 - p3)) / np.linalg.norm(p2 - p1)
（目前未解决，胆代码可以继续正常运行）
