I have created a new Gradio Space. Here is the list of dependencies in requirements.txt

torch  
transformers  
gradio\>=5.0.0  
scipy  
sounddevice  
pydub  
TTS  
wheel

The building process shows a lot of errors like this

```auto

  note: This error originates from a subprocess, and is likely not a problem with pip.

```

I’ve tried to do a Factor rebuild and Restart in Space settings, but nothing helps. I have a few questions.:

1. What are the restrictions on installing dependencies? Is there a description somewhere of what can and cannot be done with Gradio Space?
2. How do I install Gradio 5 correctly?

I hear there’s no **wheel** …

I checked thousands of lines, rebuilt the Space countless times, nothing worked. In the end, it was a dependency version conflict. Removing all version numbers fixed it. I thought I won… until the build broke again. Why? HF was missing wheel. Yes — wheel, the most basic pip package. Turned out: 503 error. Internal update. No notice. Then I found ou…

> gradio\>=5.0.0

This is enough. If you set it up as a Gradio space, you only need to set up the README.md (actually, the first half is a YAML configuration file), and you don’t need to specify it in requirements.txt.

> What are the restrictions on installing dependencies?

There are various things, but this is what is clearly stated.

Thank you very much! Once again, you’re helping me out! I figured it all out 🙂
