Geo Trace

Estoy tratando de instalar el plugin Geo Trace en Qgis y me da un error.
Primero lo busque en el administrador de complementos y no me aparece

Después descargue el .zip. De esta manera lo instale pero al querer abrirlo me pide instalar otros controladores, al hacerlo me da un error de python:
«AssertionError: Could not install mplstereonet.

Finalmente intente instala los controladores mediante los archivos .whl pero me dice lo siguiente:
C:\Users\Usuario\Downloads>python -m pip install Cython-0.29.24-cp36-cp36m-win32.whl
ERROR: Cython-0.29.24-cp36-cp36m-win32.whl is not a supported wheel on this platform.

C:\Users\Usuario\Downloads>python -m pip install Cython-0.29.24-cp36-cp36m-win_amd64.whl
ERROR: Cython-0.29.24-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform.

¿alguien me podrá ayudar?
Muchas gracias
