Python 可执行文件耗时过多

Question

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?

Answer 1

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.
