Probably Diffusers are too new and Transformers are too old, or vice versa, causing inconsistencies.  
So how about trying like:

```auto
pip install diffusers<=0.29.0

```

or

```auto
pip install transformers<=4.48.3

```

Hmm… Seems `transformers` is too old. How about like this?

```auto
python -m pip install -U pip setuptools wheel
pip install transformers==4.48.3

```

I installed the new transformers: `D:\pinokio\api\photomaker2.git\app\env\Lib\site-packages\transformers>pip show transformers Name: transformers Version: 4.48.3 Summary: State-of-the-art Machine Learning for JAX, PyTorch and TensorFlow`

but the error is still the same as in the first post :/. folder I’m doing this is correct? Does it matter?

There is an error message saying that the new version of Diffusers requires the new Transformers…  
Strictly speaking, I think it’s imported via PEFT, but I think [with the just old Diffusers will work fine with PhotomakerV2 for now](https://huggingface.co/spaces/TencentARC/PhotoMaker-V2/blob/main/requirements.txt).

Hmm, maybe [the Pinokio environment is special](https://stackoverflow.com/questions/79273647/cannot-import-name-encoderdecodercache-from-transformers)…?  
If you don’t consider the impact on other programs, this would be the easiest solution.

```auto
pip install transformers==4.46.3 diffusers==0.29.0

```
