Can't use pysr on linux

[Vahan-tech]

Hello to everyone,
When i start a symbolic regression with pysr, using Visual Studio Code on VNC, in a virtual environment made with the command "python3.12 -m venv namevenv" i get an error. Being the first start, when the installation of the newer version of juliapkg starts, I get:

WARNING: Error during initialization of module GMP:

ErrorException("PCRE compilation error: unrecognised compile-time option bit(s) at offset 0")

ERROR: PCRE compilation error: unrecognised compile-time option bit(s) at offset 0

The computer farm has this characteristics

• Operating System: Red Hat Enterprise Linux 8.10 (Ootpa)
• Kernel Version: 4.18.0-553.37.1.el8_10.x86_64
• Architecture: x86-64
• Shell: tcsh

Any idea on what is causing this ?
Thanks in advance.

It seems like you could try

LD_LIBRARY_PATH="" python3.12 your_script.py

i.e., it seems due to conflicting libraries in your environment

Thank you a lot for your response, i am quite a newbie where should i put this line of code ? in a file ? in which folder the one of my venv ?

P.s: to be more specific
python3.12 is in a folder called bin, i used "/bin/python3.12 -m venv namevenv" in my tcsh, then i move with the command cd in my venv folder and activate the venv with "source /bin/activate.csh" and the I launch vscode with a bsub

Unfortunately I don't know enough about your environment or IDE to help, sorry. Maybe reach out to help forums for whatever IDE you are using or your IT help desk (if you are doing this on your workplace machine).

As a quick hack you could put the following code in place of wherever your pysr import is

import os
ld_lib_path = os.environ["LD_LIBRARY_PATH"]
os.environ["LD_LIBRARY_PATH"] = ""  # Clear it

# Only after that, you can import pysr
import pysr

# Then, reset your LD_LIBRARY_PATH env variable
os.environ["LD_LIBRARY_PATH"] = ld_lib_path

Thank you a lot it worked, and worked even LD_LIBRARY_PATH="" python3.12 your_script.py (putting it in tcsh shell).
it generated other problems like not finding GLIBCXX_3.4.26, to resolve it I used this approach and worked:

setenv OLD_LD $LD_LIBRARY_PATH

setenv LD_LIBRARY_PATH
/............../venv_folder/julia_env/pyjuliapkg/install/lib/julia:$OLD_LD

then run my program
python3.12 script_name.py

setenv LD_LIBRARY_PATH $OLD_LD
unsetenv OLD_LD

I dind't understand quite well what happened, but now is working fine
