could someone point out to what is wrong with the following code?
import matplotlib.pyplot as plt
import pandas as pd
import numpy as np
from matplotlib import cm,colors
import tikzplotlib
max_r = 20
N_vorfs = 500
scalings = np.linspace(0.1, 5.*np.pi, N_vorfs)
X, Y = np.meshgrid(scalings, 2.*np.arange(1, max_r+1)-1.)
Z = np.arange(max_r*N_vorfs).reshape(X.shape)
fig, axs = plt.subplots(2, 1, gridspec_kw={'height_ratios': [3, 1]})
axs[0].contour(X, Y, Z)
print(tikzplotlib.get_tikz_code())
plt.show()
I get errors from tikzplotlib, namely
