1.安装python
1） no acceptable C compiler found in $PATH when installing python
解决方法：
系统基于redhat，则:
yum groupinstall "Development tools"
系统基于Debian :
apt-get install build-essential
2）
ubuntu E: Package 'libpng12-dev'或者E: Package 'libjpeg8-dev' has no installation candidate
has no installation candidate
解决方法：
libpng12-dev在Ubuntu16.04之后就被丢弃了，所以放弃用这个吧
把libpng12-dev换成libpng-dev就行了。同理 jpeg也适用。
2.安装 scipy:
1）出现 no lapack/blas sources found 错误.
解决方法：
sudo apt-get install libblas-dev liblapack-dev libatlas-base-dev gfortran
3.安装Pillow:
1）出现 The headers or library files could not be found for jpeg, a required dependency when compiling Pillow from source. 错误。
解决方法：这是pillow 3及以上就需要 “libjpeg”，因此需要安装相关依赖。
sudo apt-get install libtiff5-dev libjpeg-dev libopenjp2-7-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk libharfbuzz-dev libfribidi-dev
4.安装H5py
1） pip install h5py 下载完成后卡住不动：
解决方法：
sudo pip3 install cython
sudo apt-get install libhdf5-dev
sudo pip3 install h5py
