I have a bash script that runs a python script:
#!/bin/bash
restest-env/bin/python3 script.py $1 $2 $3
When executed from terminal, everything works fine. Instead, when executed from a Java application with:
ProcessBuilder pb = new ProcessBuilder(command, String.join(" ",commandArgs));
Process proc = pb.start();
proc.getOutputStream();
String stdout = IOUtils.toString(proc.getInputStream(), Charset.defaultCharset());
String stderr = IOUtils.toString(proc.getErrorStream(), Charset.defaultCharset());
proc.waitFor();
I get this M1 chip-related error:

So the strange thing is that python works fine while executed directly from terminal, but fails when executed from Java. I can not use conda. Any ideas?
I had the same issue where I was trying to use Java ProcessBuilder to run a terminal command to run a python project.
My command ran fine in the terminal but was not working when run from the Java program. When running command 'uname -p' I could see when the terminal was open manually I got 'arm' but when Java ran it it was 'x86_64 i386'. Basically java was running as an x86_64 process but my python install was arm so it failed.
To solve the issue I simply installed java jdk 18.0.2 and run my java program using this jdk. It worked after this
