An error occurred when running Python commands in the container.

[HwangDozz]

In the image built by envd, when you enter "python" in the command line, an error "segmentation fault (core dumped)" occurs.

Could you please tell me if this issue is in line with expectations?

[kemingy]

I have never experienced anything like that. Can you provide more details about how you build the image with envd?

[HwangDozz]

My build.envd file is as follows:

def build():
    base(image="docker.io/nvidia/cuda:12.8.1-cudnn-runtime-ubuntu22.04")
    install.conda()
    install.python(version="3.9")
    install.apt_packages(["openssh-server", "git", "vim", "zsh"])
    config.repo(
        url="https://github.com/tensorchord/envd",
        description="envd quick start example",
    )
    config.pip_index(url = "https://pypi.tuna.tsinghua.edu.cn/simple")
    run(commands=[
        "chsh -s /bin/zsh root;",
        "git clone --depth 1 https://mirrors.tuna.tsinghua.edu.cn/git/ohmyzsh.git;",
        "ZSH=\"/usr/share/.oh-my-zsh\" CHSH=\"no\" RUNZSH=\"no\" REMOTE=https://mirrors.tuna.tsinghua.edu.cn/git/ohmyzsh.git sh ./ohmyzsh/tools/install.sh;",

    ])
    config.jupyter()

I can reproduce this with:

def build():
    base(image="ubuntu:22.04")
    install.conda()
    install.python()

From the dmesg -T:

This is a very typical error caused by the locale. A simple solution is to run:

export LANG=C.UTF-8
export LC_ALL=C.UTF-8

envd has all the correct configurations for dev=True. I will fix this for dev=False.

Fixed in version 1.2.0
