2-1. Trouble shoot

(1) OSError: PortAudio library not found If you get the message below, you shold install additional library.

OSError: PortAudio library not found

You can install the library this command.

$ sudo apt-get install libportaudio2
$ sudo apt-get install libasound-dev

(2) It's not starting up! Damn software!

The client will not start automatically. Please launch your browser and access the URL displayed on the console. And watch your words.

(3) Could not load library libcudnn_cnn_infer.so.8

When using WSL, you might encounter a message saying Could not load library libcudnn_cnn_infer.so.8. Error: libcuda.so: cannot open shared object file: No such file or directory. This often happens because the path hasn't been properly set. Please set the path as shown below. It might be handy to add this to your launch script, such as .bashrc.

export LD_LIBRARY_PATH=/usr/lib/wsl/lib:$LD_LIBRARY_PATH

Also run these command.

pip install chardet
pip install numpy==1.24.0

For Client Developer
