import numpy exception in sharedInterpreter using jep #536

Closed Dynasty-develop closed 1 month ago

Dynasty-develop commented 1 month ago

Problem 1.jep.JepException: <class 'ImportError'>: Error importing numpy: you should not try to import numpy from its source directory; please exit the numpy source tree, and relaunch your python interpreter from there. 2.jep.JepException: <class 'ImportError'>: /usr/local/python3/lib/python3.10/lib-dynload/_posixsubprocess.cpython-310-x86_64-linux-gnu.so: undefined symbol: PyTuple_Type

Environment :

Centos 7 Python 3.10.14 Java Distribution and Version: jdk 8 Jep Version: jep-4.2.0 Python packages used : numpy, cv2, onnxruntime, torch, skimage

I suceed to install JEP/Java/python environment. My project is working fine in my local Windows computer. When I deploy the project to Centos 7 and use jep to call python script, I am getting "Import Error". But I directly run the python script, its alse work abnormally. I am completely confused and dont know how to solve this trouble.

Troubleshooting: sys.path from jep: [/usr/local/python3/lib/python310.zip, /usr/local/python3/lib/python3.10, /usr/local/python3/lib/python3.10/lib-dynload, /usr/local/python3/lib/python3.10/site-packages, /home/xxx/xxx/xxx/xxx]

JEP:

(jep is installed under the site-packages) Observations: I can see the interpreters is initialized but when function call goes, I am getting the "Import Error"

Please help! thank you!

The ultimate reason is that it was not compiled correctly the Python source code package, it caused to lack the libpython3.10.so file and jep can`t work normally. So the solved method is recompile Python source code package with the command "./configure --prefix=/usr/local/python3 --with-openssl=/usr/local/openssl --enable-shared". After do this, anything work fine.
