I have the following settings:

  • Pythonnet version: 2.3.0, installed with pip in Amaconda3
  • Python version: 3.6.6 using with Anaconda 3
  • Visual Studio 2017 Community
  • Operating System: Windows 7, 64 bit

I run this code, and it pops out this error.

using (Py.GIL())
{
                dynamic np = Py.Import("numpy");
                Console.WriteLine(np.cos(np.pi * 2));

                dynamic sin = np.sin;
                Console.WriteLine(sin(5));

                double c = np.cos(5) + sin(5);
                Console.WriteLine(c);

                dynamic a = np.array(new List<float> { 1, 2, 3 });
                Console.WriteLine(a.dtype);

                dynamic b = np.array(new List<float> { 6, 5, 4 }, dtype: np.int32);
                Console.WriteLine(b.dtype);

                Console.WriteLine(a * b);
                Console.ReadKey();
}

result :

1.0
-0.9589242746631385
-0.675262089199912
object

error occurs here :
dynamic b = np.array(new List { 6, 5, 4 }, dtype: np.int32);"

I get the following error:
Python.Runtime.PythonException: 'TypeError : int() argument must be a string, a bytes-like object or a number, not '0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]''

python setup.py bdist_wheel --xplat
pip install dist\pythonnet-2.4.0.dev0-cp36-cp36m-win64.whl

python setup.py bdist_wheel failed because need import error : mt.exe could not be found
I did not restart my pc while installing Visual Studio 2017 Community.
So, i think that Visual Studio 2017 Installer did not install mt.exe for me.

while running on Visual Studio 2017 that fully installed, i found this issue in python setup.py bdist_wheel --xplat

Would like to ask that, is there any option to solve this ? Thank you,

@STREETKILLER007 just grab the wheels from appveyor ci artifacts, in VS 2017 you probably do not have the C/C++ compilers installed. You can search for mt.exe in Windows Explorer and report back the path if you have it.

Then what is the path for mt.exe on your machine?

@denfromufa

The location of mt.exe is as below

C:\Program Files (x86)\Windows Kits\10\bin\10.0.17134.0\arm64
C:\Program Files (x86)\Windows Kits\10\bin\10.0.17134.0\x64

@STREETKILLER007 try updating vswhere.exe in pythonnet\tools. It is possible that some new VS 2017 paths were added recently:

https://github.com/Microsoft/vswhere/releases

But it should be easier to grab binaries from appveyor.

Hmm, i read the github page.

But i did not see any installation steps.

Would like to ask some help here...

I choose Environment: PYTHON_VERSION=3.6, BUILD_OPTS=--xplat; Platform: x64 and press archieve.
After that, i run pip install pythonnet-2.4.0.dev0-cp36-cp36m-win64.whl

than i run back the example, it works nice.

pythonnet is version 2.4.0.de

Thank for the help.

I am trying to do this example another machine in cyber cafe.
When install Visual Studio in that machine, i will choose the same things to install.
i will not restart it since if i restart, the machine will reset to its default state.

in that machine, i can't find mt.exe.

When pip install pythonnet-2.4.0.dev0-cp36-cp36m-win64.whl, it still works fine.

run example in that machine.

It showed same result, works nice.
