Hi, I have value error: This tokenizer cannot be instantiated. Please make sure you have `sentencepiece` installed in order to use this tokenizer. I installed and updated `sentencepiece` (0.1.95) but still getting the same error. Can someone help? Thank you! ---

Hi @Katarina, what happens if you try installing `transformers` in a new environment with ```auto pip install transformers[sentencepiece] ``` Does that solve the problem? ---

this has to do with you shell actually. You are probably using zsh if you are on Mac, and you are getting `zsh: no matches found: transformers[sentencepiece]`. Solution: `pip install "transformers[sentencepiece]"` ---

Fix: ` pip install transformers[sentencepiece]` if it is installed and still getting error, restart the kernel ---

Use pip install transformers[sentencepiece] And restart the kernel. It will work 🙂 ---

I also found that using conda install works. I had to do conda install sentencepiece and conda install protobuf to get it to work for me. ---

Besides conda install sentencepiece, I found that I can do conda install sentence-transformers which pull in sentencepiece also. ---

# Yes, I met this issue either. My platform is below: MacOS 15.0.1 Python 3.12.6 pip 24.2 Then I executed this command: ```auto pip3 install sentencepiece ``` And restarted Kernel, then it works ---

For those who find this thread before others across the web, sentencepiece is currently failling install in python 3.13. Other threads suggest that installing 3.12 can resolve the issue and allow for the install to complete. > `sentencepiece` does not support `python 3.13` yet. > Its latest version was released on Feb 19, 2024. > You need to downgrade to `python 3.12` > **[sentencepiece · PyPI](https://pypi.org/project/sentencepiece/)** also, for those new to python, you can have more than one python version installed at the same time. > If you have multiple versions of python installed, don’t forget to use “py --list” to see which ones you got. As an example, after discovering that the issue is with python 3.13, I explicitly told it to use update 3.11 as follows: “py -3.11 -m pip install -r requirements.txt” This got through the sentencepiece part of my requirements file quotes copied from [here](https://stackoverflow.com/questions/78009310/i-can-not-install-sentencepiece-how-to-solve-it)
