For me安装失败，原因是error: command 'gcc' failed with exit status 1. 这对我很有用：

pip install cython
pip install git+https://github.com/lucasb-eyer/pydensecrf.git

安装cython是您需要尝试的第一件事。仅此一点对我来说不起作用。两者的结合就像一种魅力

步骤1：从链接https://anaconda.org/conda-forge/pydensecrf/files?version=1.0rc2&page=2下载与python版本兼容的pydensecrf包步骤2：提取包并将文件夹“Lib”中的两个子文件夹“pydensecrf和pydensecrf-1.0rc2.dist info”复制到python的已安装文件夹（例如：C:\python 3.6\Lib\site packages）
