Latex does not work in Python's matplotlib

I installed MikTex and try to plot some graphs using Matplotlib. There, I want to use Latex, but I get the following error:

 File "C:UsersLeoanaconda3libsite-packagesmatplotlibtexmanager.py", line 277, in _run_checked_subprocess
   stderr=subprocess.STDOUT)

 File "C:UsersLeoanaconda3libsubprocess.py", line 411, in check_output
   **kwargs).stdout

 File "C:UsersLeoanaconda3libsubprocess.py", line 512, in run
   output=stdout, stderr=stderr)

CalledProcessError: Command '['latex', '-interaction=nonstopmode', '--halt-on-error', 'C:UsersLeo.matplotlibtex.cached97ff769cca1b07656427b11e7187cec.tex']' returned non-zero exit status 1.


The above exception was the direct cause of the following exception:

RuntimeError: latex was not able to process the following string:

Here is the full report generated by latex:
failed to create process. 

I have installed TexLive and can call it from the commmand prompt by typing latex. It is located in the folder C:texlive

I have previously installed MikTex and been trying to solve this for hours now, please help me!
