I am using Standalone Spyder 5.3.3 version and running all the packages from pip install without anaconda. Instead of conda, I use Python 3.97 in the my C drive “C:\Python39” folder with all the necessary packages installed in the same folder.  
How can I configure G++ for Aesara in Pymc 4.17 🤔  
**Versions: (all the required packages are updated to the latest)**  
pymc: 4.17  
spyder: 5.3.3  
python:3.9.7  
**P.S.:** I have also installed m2w64 toolchain program in my C drive. And the conda option using `conda install m2w64-toolchain` is not working for me.

**Warning Code** :

```auto
import pymc as pm 
WARNING (aesara.configdefaults): g++ not available, if using conda: `conda install m2w64-toolchain`
WARNING (aesara.configdefaults): g++ not detected! Aesara will be unable to compile C-implementations and will default to Python. Performance may be severely degraded. To remove this warning, set Aesara flags cxx to an empty string.
WARNING (aesara.tensor.blas): Using NumPy C-API based implementation for BLAS functions.
