I had the same issue in Colab. My code is as follows

```auto
!pip install -q gradio
import gradio

```

I try to run the same code in Kaggle. There are some Warning messages:  
“ERROR: pip’s dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts…”  
I modified my code:

```auto
!pip install -q gradio --use-deprecated=legacy-resolver

```

Everything is fine.

Oh! I got a solution from CSDN. It can fix the above error in Colab. Try to install gradio with the version of 3.45.0.

```auto
!pip install -q gradio==3.45.0

```
