Pillow-SIMD：经过针对SIMD(单指令多数据)指令优化的Pillow包
Pillow-SIMD vs Pillow, AVX2的Pillow-SIMD几乎比Pillow快3~10倍

Pillow-SIMD vs others

Pillow-SIMD 与 Pillow不能共存，安装Pillow-SIMD前，请先卸载掉Pillow

pip uninstall pillow

然后从https://www.lfd.uci.edu/~gohlke/pythonlibs/#pillow-simd，下载对应Python版本的AVX2编译版本，例如：Python3.7.7， 64bit，则下载Pillow_SIMD-7.0.0.post3+avx2-cp37-cp37m-win_amd64.whl
用命令：

pip install "Pillow_SIMD-7.0.0.post3+avx2-cp37-cp37m-win_amd64.whl"

即可完成安装。验证安装，参考下图
