How to install the libtvm.dll？

[Arthur-Shi]

I cannot install successfully because

Traceback (most recent call last):
File "setup.py", line 28, in
LIB_PATH = libinfo'find_lib_path'
File "./tvm/_ffi/libinfo.py", line 85, in find_lib_path
str('\n'.join(lib_dll_path + runtime_dll_path)))

C:\tvm-master\build\Release\tvm_runtime.dll
C:\tvm-master\lib\tvm_runtime.dll
C:\tvm_runtime.dll

I think it is due to fail to build the Shared Library, isnot it？

But how can I install the libtvm.dll?

You need to build libtvm.dll with CMake, see http://docs.tvmlang.org/how_to/install.html#building-on-windows

I had installed successfully,
C:\tvm-master\build>cmake -G "Visual Studio 15 2017 Win64" -DCMAKE_BUILD_TYPE=Release -DCMAKE_CONFIGURATION_TYPES="Release" ..
-- Build with RPC support...
-- Build with Graph runtime support...
-- Configuring done
-- Generating done
-- Build files have been written to: C:/tvm-master/build

But still

C:\tvm-master\python> python setup.py install --user

What should I do?

[tqchen]

Please double check if the file is already in the path listed in the candidate

[tqchen]

After you build cmake in windows, you will need to open visual studio and compile that with VS

[Arthur-Shi]

Yes, I cannot find these files listed. and what it compiling that with VS?
I had tried run the tvm.sln in the build folder by VS, But nothing changed.

I am so sorry about these stupid questions, Thank you for your patient reply so much.

[tqchen]

YOu need to open the solution and do build in visual studio to create the dll

[Arthur-Shi]

Thanks for your help,
I installed it successfully,
