Issue Installing janus with gradio Extra: sentencepiece Build Fails

[gnatsum1]

I'm encountering an issue while trying to install the janus package with the gradio extra using the command:

pip install -e .[gradio]

The installation fails during the build process for the sentencepiece package with the following error:

error: ‘absl::string_view’ has not been declared
error: command '/usr/bin/x86_64-linux-gnu-g++' failed with exit code 1

I had an error too -- don't remember teh exact error message, but it was also related to sentencepiece Build Failure.
I solved this issue by installing the correct version of sentencepiece:

Download, build, and install the correct version of sentencepiece.

• CheckJanus\requirements.txt to get the version of sentencepiece. It is 0.1.96 in my case.
• Clone the correct version
• Make and build
• Install

Commands are below:

git clone https://github.com/google/sentencepiece.git --branch v0.1.96 --single-branch
cd sentencepiece
mkdir build
cd build
cmake .. -DSPM_ENABLE_SHARED=OFF -DCMAKE_INSTALL_PREFIX=".\root"
cd ..\python
python setup.py bdist_wheel		
set INCLUDE=%INCLUDE%;C:\Projects\sentencepiece\build\root\include
	

Now install Gradio and it runs fine:
pip install -e .[gradio]
