Matplotlib/ezdxf Font not found after compile

[luanfreire]

I'm using this code to convert a DXF to PDF Everything works fine when I run it inside my IDE. But when I create an exe file (with auto-py-to-exe) The console prints this error many times: findfont: Font family 'txt_____' not found.

import ezdxf
import matplotlib.backends.backend_pdf
from ezdxf.addons.drawing.matplotlib import qsave
from matplotlib.backends.backend_pdf import PdfPages
from ezdxf.addons.drawing.config import Configuration

doc = ezdxf.readfile('dxfs/test.dxf')
msp = doc.modelspace()

config = Configuration.defaults()

qsave(msp, 'test.pdf', bg='#FFFFFF', config=config, backend="pdf")

PS:. When I run it inside VSCode the PDF is created and the font is correct (Txt). When I run the exe file the pdf is also created (after the error message is shown many times on the console) but with Arial font.
