This error message can appear in various situations, including when using command-line programs or scripts. This error indicates that a subprocess started by a primary process exited with an unexpected or non-zero code, indicating a failure or an exception.

This error can arise in a variety of contexts, including:
Using pip to install or create a package: If you try to install or build a Python package with pip, you may encounter this error if some dependencies or requirements, such as numpy, subsystems, or tensorflow2345, are not met.
Using vGPU to power up a virtual machine: When attempting to turn up a virtual machine that employs NVIDIA RTX A6000 or NVIDIA A40 GPUs with vGPU software, you may see this problem. This issue is triggered by an insufficient memory allocation for the GPUs’ virtual functions (VFs).

Quick Fix To resolve this error, modify the /etc/vmware/config file and insert the following line: pciPassthru0.cfgNumVFs = “16” (or higher).

Then, restart the host and try to restart the virtual machine. This helps you understand and correct the problem. If you require additional assistance, please offer more information about your circumstance as well as the output of the subprocess.
