Question

I have encountered below issue when installing the CVXPY, I have also downloaded the lasted version of visual studio but seems not working either.

I faced the same issue. I had to create a new environment and install for it to work. Go to Anaconda Prompt, and do:

conda create your_env_name
conda activate your_env_name
conda install -c conda-forge cvxpy
conda install spyder

I use Spyder for my work. I had to install Spyder in the new environment as in step 4. I could not find a work around to use the existing Spyder to work for both environments.
