I have a python code to search in pdf documents. When I run the .py file, it executes fine. However, i have made an executable file with pyinstaller. this exe file is taking too long to open - almost 10 minutes. What could be the reason?

  • How large is the EXE? How did you ever manage to wait 10 minutes for it to start? How did you measure that? I would suggest looking into it with [Process Monitor](https://learn.microsoft.com/en-us/sysinternals/downloads/procmon) – Thomas Weller Mar 19 '21 at 07:58
  • Since you have not mentioned your application structure and the size of your executable the best I can suggest is to exclude all the unnecessary files and prune the unused imports while you package your app. – NIV Mar 19 '21 at 08:29

10 minutes is very very long. But it you build a single executable with pyinstaller, it will uncompress itself into a temp folder everytime it starts. That folder will contain the required libraries a modified version of the Python interpretor and your own code in pre-compiled form. If you use a slow disk unit or have little space on it, it will indeed take time.

A possible way to speed up the start time is to have pyinstaller build a folder. This will save the initial uncompressing time.
