Besides, this dependency

rtree >=0.8.3                :  0.8.3 (OK)

shows that you’re using Anaconda, but by running these commands

pip install sympy
pip install cython
pip install matplotlib
pip install pandas
pip install numpy
pip install scipy

instead of

conda install sympy
conda install cython
conda install matplotlib
conda install pandas
conda install numpy
conda install scipy

you broke your Anaconda installation and now you have to reinstall it. That’s because pip and conda packages are incompatible for the most part.

So from now on please use conda first to install packages and only use pip if they are not available through conda.

Sorry I meant to clarify that when ran the conda install sympy in the Anaconda Prompt I got “All requested packages already installed” however after that when I relaunched Spyder 4 it was still marked with a warning. The only way I could get the warning to disappear was to use the pip install sympy within the Spyder 4 console.
