Error running an exe file in Windows with reportlab import

[Ernest Bonat, Ph.D.]

I have created a simple Python program including the following packages:



import numpy as np

import matplotlib.pyplot as plt

import pandas as pd

from reportlab.pdfgen import canvas



if __name__ == '__main__':

    print("Hi!")



I have created the installation package (PyInstaller) using the following
command line:



pyinstaller --onedir --name=runatestapp --noupx
"C:\Users\Ernest\workspace\bars\src\run_a_test.py"



The required folders (build and dist) and the spec file are created
properly with no errors. When I run the runatestapp.exe file in the command
prompt I got the error "Failed to execute script run_a_test".



I'm using the following software versions now:



Anaconda3 4.1.1.64-bit

Python 3.5.2

PyInstaller 3.2

Windows 10 64-bit



Here is the Traceback info
