py faster rcnn,UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position 10: ordinal not

cd /usr/lib/python2.7/

sudo gedit posixpath.py

然后加上三行代码：

import sys
reload(sys)
sys.setdefaultencoding('utf8')

重新运行就可以了，亲测运行通过：

idc@idc-Hi-Fi-Z77X:~/Text-Detection-with-FRCN/py-faster-rcnn/lib/utils$ cython bbox.pyx

另外当你在py faster rcnn的lib目录下运行make的时候，解决方式跟上述一样的

idc@idc-Hi-Fi-Z77X:~/Text-Detection-with-FRCN/py-faster-rcnn/lib$ ls
build     fast_rcnn  nms          roi_data_layer  setup.py   utils
