I've already installed LaTeX via pip and I've also installed the software from http://www.tug.org/. But still, I can't design a plot using ChainConsumer and it gives me the error "Failed to process string with tex because latex could not be found." What can I do to solve the problem?
here is my code:
import pandas as pd
import numpy as np
!pip install chainconsumer
!pip install latex
from chainconsumer import ChainConsumer
df2= pd.read_csv('height_weight.csv')
params = ["weight", "height"]
m = df2['sex']==1
male = df2.loc[m, params].values
female = df2.loc[~m, params].values
c = ChainConsumer()
c.add_chain (male , parameters = params, name = "male", kde = 1.0, color = "r")
c.add_chain (female , parameters = params, name = "female", kde = 1.0, color = "b")
c.configure (contour_labels = "confidence")
c.plotter.plot(figsize = 2.0)
and here's the error:

This is an open issue in ChainConsumer, and can be fixed by adding the
usetex = Falseflag when configuring your plot.In your example:
