Dear Pyinstaller and Matplotlib users.
Found this problem with my project
Matplotlib and Tkinter based application with export to PDF works great
until you compile it to Exe file by PyInstaller. So I made simple app that
show the problem:
When execute Exe file and try to export pdf file - program drop this error
text to console:
ModuleNotFoundError: No module named ‘matplotlib.backends.backend_pdf’
P.S. Importing this “matplotlib.backends.backend_pdf” module in code does
not help
My configuration:
Python 3.11.9 x64
Matplotlib 3.9.2
PyInstaller 6.10.0
Command to compile: pyInstaller.exe SaveToPdfApp.py --onedir --noconsole
--noconfirm --noupx --console
Simple sample code:
*import tkinter as tkfrom tkinter import filedialogfrom
matplotlib.backends.backend_tkagg import FigureCanvasTkAggimport
matplotlib.pyplot as pltimport numpy as np#from
matplotlib.backends.backend_pdf import PdfPagesdef save_plot_as_pdf():
file_path = filedialog.asksaveasfilename(defaultextension=".pdf",
filetypes=[("PDF files", "*.pdf")]) if file_path: #with
PdfPages(file_path) as pdf: #pdf.savefig(figure)
figure.savefig(file_path, format="pdf") print(f"Plot saved as
{file_path}")root = tk.Tk()root.title("Matplotlib Plot in Tkinter")x =
np.linspace(0, 10, 100)y = np.sin(x)figure = plt.Figure(figsize=(6, 4),
dpi=100)ax = figure.add_subplot(111)ax.plot(x, y, label="Sine
wave")ax.set_title("Simple Sine Wave
Plot")ax.set_xlabel("X-axis")ax.set_ylabel("Y-axis")ax.legend()canvas =
FigureCanvasTkAgg(figure, root)canvas.get_tk_widget().pack(side=tk.TOP,
fill=tk.BOTH, expand=1)save_button = tk.Button(root, text="Save as PDF",
command=save_plot_as_pdf)save_button.pack(side=tk.BOTTOM)root.mainloop()*
