Is anyone familiar with koyha and how to get it to work? I am following the guide

https://aituts.com/stable-diffusion-lora/#Train_your_own_LoRA

During step 3, the command

cp .\bitsandbytes_windows.dll .\venv\Lib\site-packages\bitsandbytes\

returns the error

cp : The filename, directory name, or volume label syntax is incorrect. At line:1 char:1

• cp .\bitsandbytes_windows.dll .\venv\Lib\site-packages\bitsandbytes ...

•  undefined

Does anyone know how to go about dealing with this?
