Thanks for your reply!
I follow the instructions to build from source, and when “python setup.py install” meet cmake error as shown in the figure:

cmakeerror1897×1575 44.9 KB

It seems that the C++ compiler cannot to compile a sample  test program. But I installed Visual Studio 2019, the compiler should be the latest,  why is the error happend?  The conda list is also shown at the end of the fig. How to fix this error?
Thank you.
