Hi, I believe this is a duplicate of #47, so I'm closing this one in order to keep a single issue for this problem.

Unfortunately, I currently do not have access to a windows development machine, so I cannot help. The error message is "系统找不到指定的文件" and means "The system can not find the file specified", correct? What file is it about? I don't understand the error here.

Maybe just a guess: did you install a recent version of Cython? Did you check both options linked here in the README?

Step1: download package of pydensecrf compatible with python version from link https://anaconda.org/conda-forge/pydensecrf/files?version=1.0rc2&page=2 Step2: Extract the package and copy two subfolders "pydensecrf and pydensecrf-1.0rc2.dist-info" in folder "Lib" to installed folder of python (Example: C:\Python 3.6\Lib\site-packages)
