I get an error (prefix must not be bound to one of the reserved namespace names) when trying to render an inline svg.

import io

import numpy as np
import weasyprint
from matplotlib.figure import Figure

np.random.seed(7)
data = np.random.randint(0, 1_000, size=(10, 2))

fig = Figure()
ax = fig.add_subplot()
ax.plot(data)

buffer = io.StringIO()
fig.savefig(buffer, format='svg')
img = f"<svg {buffer.getvalue().split('<svg ')[1]}"
html_str = f"""
<html>
  <head></head>
  <body>
    {img}
  </body>
</html>
"""
weasyprint.HTML(string=html_str).write_pdf('example.pdf')
