ImportError: Interpreter change detected - this module can only be loaded into one interpreter per process.

I like to use this in Siemens NX during Manufacturing Machine Simulation because I wrote my own Python files. If I run a journal then I can setup the script with Global Interpreter Lock and the encrypted script works perfectly a couple of times after eachother.
If I do simulation I cannot force GIL so the first time the encrypted scipts get decrypted by the loader. The second time I get "ImportError: Interpreter change detected - this module can only be loaded into one interpreter per process." and the encrypted scipt does not get decrypted because the loader is not loaded again. Whatever I do, I cannot get it to work a second time.

Hi! The loader doesn't need to be loaded again. It simply inserte EncryptFileFinder to sys.meta_path once.
Can you provide more information, such as a small demo?

pyencrypt-pye/pyencrypt/loader.py

Line 97 in 32db20c

sys.meta_path.insert(0, EncryptFileFinder())

Hi, I have attached to log files from Siemens NX. In the 1st-time.txt you see a lot of modules loaded and the encrypted files are decrypted. The 2nd-time.txt shows a lot less modules loaded. You see that loader is still loaded but not cython and a lot of others. So the files are not decrypted.

I didn't find any logs related to ImportError in the traceback you provided.

[Bird23]

Hi, The attached logs are from the most simple use as in....encrypt files and import loader. Then first time it works, second time not. The Importerror: Interpreter change detected.....I have to change my script a little bit, but I can't remember what I changed in the script. I have to figure this out again. I will come back to you, when I have it. Regards, Jacco Op ma 2 sep 2024 om 05:46 schreef Qi Zhao ***@***.***>:

Hi, Good news. Your pyencrypt is working now. The problem was that the loader was kept open(in use) by windows the first time and was not loaded (executed) again. The solution is, with a little bit of python code, closing the file-handle of the loader. Now it gets loaded again. Thanks for your very nice pyencrypt module.

The problem was that windows was keeping the loader in-use. Due to a few simple lines of code, the loader's file-handle is released, so the loader can start again.

[Bird23]

Hi, One final question. Since I can use pyencrypt now, when do you think that you have added the loader name option to pyencrypt? Best regards, Jacco Op wo 25 sep 2024 om 10:14 schreef Jacco Loonstra ***@***.***
