For adding data files you need to First, provide your data files with --add-data flag. Then because your data would be extracted on a temp directory, you need to set its address for your app. In below example, I'm addressing all CSV files from resource_path function which would return the relative path for each file.
I assume that you put all your files in data directory beside your app.
app.py:
import os
import sys
def resource_path(relative_path):
if hasattr(sys, '_MEIPASS'):
return os.path.join(sys._MEIPASS, relative_path)
return os.path.join(os.path.abspath("."), relative_path)
if __name__ == "__main__":
csv_files = ["data/a.csv", "data/b.csv", "data/c.csv"]
print("Reading CSV files from data directory")
for csv_file in csv_files:
with open(resource_path(csv_file), "r") as f:
print(csv_files, ":", f.read())
print("Done!")
You can then generate your executable with:
pyinstaller app.py -F --add-data "./data/*;data/"
