@yxdragon can you take a look?

it seems the geos package can't be installed. You may try to install this package independently and then return to condo to install imagepy.
My experience is that when I install imagepy with condo, it says that the pystackreg can't be installed and conda stoped to install imagery. I copy the pystackreg from the Pre-compiled package of imagpy (https://github.com/Image-Py/imagepy/releases) into the imagepy install direction. Then reinsitall imagepy again. Now the conda doesn't check pystackreg and successfully install imagery.

It is the matter of shapely, try the binary whl?

缺少geos_c.dll模块，在https://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely，下载对应版本的Shapely的whl文件，重装即可。
Missing geos_ c. dll, Download the corresponding version of shapely's whl file and reinstall it in https://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely.
