使用pyinstaller打包python程序出现“NoModuleFindError”

Question

I use pyinstaller to package my python program into executable program(exe).

my program version:

Pyinstaller :3.3.1

Python :3.6.1 Windows:10-10.0.16299-SP0

---

I can run the data_processing_gui.py file with the command "python data_processing_gui.py" in my command-line window without any ERROR.

---

I use the command to package my python program(which name is data_processing_gui.py):

pyinstaller -F -p C:\Users\fanyu\Anaconda3\Lib;C:\Users\fanyu\Anaconda3\Lib\site-packages;C:\Users\fanyu\Anaconda3\Lib\site-packages\PyQt5\Qt\bin;C:\Users\fanyu\Anaconda3\Lib\site-packages\pydicom;C:\Users\fanyu\Anaconda3\Lib\site-packages\radiomics;C:\Users\fanyu\Anaconda3\Lib\site-packages\pywt;C:\Users\fanyu\Anaconda3\Lib\site-packages\pywt\_extensions;C:\Users\fanyu\Anaconda3\Lib\site-packages\tensorflow;C:\Users\fanyu\Anaconda3\Lib\site-packages\SimpleITK;C:\Users\fanyu\Anaconda3\Lib\site-packages\PIL;C:\Users\fanyu\Anaconda3\Lib\site-packages\pandas;C:\Users\fanyu\Anaconda3\Lib\site-packages\nrrd;C:\Users\fanyu\Anaconda3\Lib\site-packages\numpy -i C:\Users\fanyu\Desktop\work\package\image\doctor.ico data_processing_gui.py

There is no ERROR when I run code above in windows' command-line window,but when I run the target program(data_progressing_gui.exe),there is a ModuleNotFindError ,the error infomation is:

Traceback (most recent call last): File "data_processing_gui.py", line 12, in File "c:\\users\\fanyu\\anaconda3\\lib\\site-packages\\PyInstaller\\loader\\pyimod03_importers.py", line 631, in exec_module exec(bytecode, module. dict ) File "site-packages\\radiomics__init__.py", line 15, in File "c:\\users\\fanyu\\anaconda3\\lib\\site-packages\\PyInstaller\\loader\\pyimod03_importers.py", line 631, in exec_module exec(bytecode, module. dict ) File "site-packages\\radiomics\\imageoperations.py", line 6, in

It seems like the program can't find the specify package path(pywt._extensions._cwt),however,I've added the path in the pyinstaller's parameter list.

At first,I think maybe there is something wrong with my pyinstaller,so I've tried to reinstall it. Then I write a simple python program to test it,it runs correctly.

I've tried a lot but just can't solve it,so I am here to ask for help,I will appreciate it if anyone can give any advice.

Answer 1

I find a solution for my problem in the answers to the following question ModuleNotFoundError: No module named 'pandas._libs.tslibs.timedeltas'

I can't explain why but it does solve my problem.

The solution is: After generating the ".spec" file using pyinstaller,add the missing module into the ".spec" file at "hiddenimport=[]",like this:

hiddenimport=["pywt","pywt._estentions._cwt"]

Then use this file to generate your exe file:

pyinstaller my.spec
