But before we start, I recommend to: Install miniconda for dependency sanity wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh && sudo chmod +x Miniconda3-latest-Linux-x86_64.sh && bash Miniconda3-latest-Linux-x86_64.sh Setup PyTorch environment as needed and confirm with python -m torch.utils.collect_env ...

In the past, I have covered how to set up Ubuntu in WSL2 and hosting local LLMs with Harbor, now I want to migrate my Harbor instance from baremetal Linux into WSL2 so that I don’t have to set it up from scratch. First thing to do is to open firewall port netsh interface portproxy add v4tov4 listenport=33811 listenaddress=0.0.0.0 connectport=33801 connectaddress=172.xx.xxx.xxx On Linux hardware: copy Harbor files from /home/username/Harbor /home/username/.ollama On Windows hardware: connect the USB drive containing Harbor files and run ...
