linux上cython编译错误

在Linux上cython编译遇到问题：

python setup.py build_ext --inplace

问题如下：
running build_ext
skipping ‘bbox.c’ Cython extension (up-to-date)
skipping ‘nms.c’ Cython extension (up-to-date)

首先，发现python是3.7，所以需要将python版本换为3.5即可
可通过如下来创建一个conda虚拟环境

conda create -n conda-env python=3.5
conda activate conda-env
conda install -c anaconda cudatoolkit=10.0
conda install cudnn
pip install numpy1.16.4
pip install tensorflow_gpu1.13.1
pip install cython
pip install pillow
pip install opencv-python

然后再编译就可以了。
