1. 简介
gotrackit是一个地图匹配包, 基于隐马尔可夫模型(Hidden Markov Model)实现
1.1. 如何安装gotrackit
所需前置依赖
- geopandas(0.14.1)
- gdal(3.4.3)
- networkx(3.2.1)
- shapely(2.0.2)
- pandas(2.0.3)
- numpy(1.26.2)
- pyproj(3.6.1)
- keplergl(0.3.2)
括号中为作者使用版本(基于python3.11), 仅供参考
geopandas为最新版本, 如果不是最新版本可能会报错(有个函数旧版本没有)
使用pip安装
pip install -i https://test.pypi.org/simple/ gotrackit==0.0.2
