Change font for both labels and ticks on 3d surface plot-CodePudding

For the code below, how do I go about changing the font of all the labels and ticks to a font that is recognized by matplotlib.font_manager? I wanted to change it to URW Palladio L font, but I do not know the font family etc. as I tried this command:

plt.rcParams.update({'font.size': 18, 'font.family': 'serif', 'mathtext.fontset': 'URW Palladio L'})

but got the error:

ValueError: Key mathtext.fontset: 'URW Palladio L' is not a valid value for mathtext.fontset; supported values are ['dejavusans', 'dejavuserif', 'cm', 'stix', 'stixsans', 'custom']

Here is an example code:

from mpl_toolkits.mplot3d import Axes3D

from matplotlib import cbook
from matplotlib import cm
from matplotlib.colors import LightSource
import matplotlib.pyplot as plt
import numpy as np


# Set up plot
# Update the matplotlib configuration parameters:
#plt.rcParams.update({'font.size': 18, 'font.family': 'serif', 'mathtext.fontset': 'URW Palladio L'})
fig = plt.figure(figsize=(15, 12))
fig, ax = plt.subplots(subplot_kw=dict(projection='3d'), figsize=(15, 12))

ax.set_title(f'{graph_title}')
ax.set_xlabel('Frequency (Hz)', labelpad=20)
ax.set_ylabel('Time (s)', labelpad=20)
ax.set_zlabel('PSD Amplititude (dB/Hz)', labelpad=20)

ax.view_init(20, 20)
plt.show()
