After installation python still raising ModuleNotFoundError

[HaoLuo2627]

After I ran the command "pip install lmstudio", my program still raises ModuleNotFoundError. When I see the site-packages folder in my virtual environment, there is only a "lmstudio-0.0.1.dist-info" folder, and there is no "lmstudio" source code folder with "init.py" in it. I changed the pip index url from "https://mirrors.aliyun.com/pypi/simple" to "https://pypi.org/simple", but the error still exists. Please check the issue and give me some suggestions, thank you!

Had you previously tried installing lmstudio into that virtual environment prior to 2025-02-28? (Feb 28 is when lmstudio 1.0.0 was published to PyPI).

Before then, lmstudio 0.0.1 only existed as a placeholder distribution package with no actual contents, and your dist-info folder name indicates that is the version that is currently installed in the virtual environment.

Regardless, running pip install --upgrade lmstudio should replace the placeholder installation with the latest version.

No, today is my first installation attempt.
After I ran pip install --upgrade lmstudio, pip raises Requirement already satisfied: lmstudio in c:\users\luohao\.conda\envs\opencompass\lib\site-packages (0.0.1) both from index urls pypi.org and mirrors.aliyun.com. It seems that pip hasn't found the lmstudio in version 1.0.0.

I figured it out, maybe it's because my Python version is 3.10. When I changed a different virtual environment with Python 3.12, the installation succeeded. Thank you for your response.

Follow up:

• 1.1.0 added Python 3.10 support
• the placeholder package that was being installed on older versions has been yanked (so 3.9 and earlier will now get an installation failure)
