Starting container
Installing spikeinterface with github in container

Start by reproducing the reported command using ss.run_sorter with the kilosort2_5 Docker image and SPIKEINTERFACE_DEV_PATH set. Trace the installation_mode='auto' path and the container's environment handling. Done means a configured SPIKEINTERFACE_DEV_PATH is honored instead of installing SpikeInterface from GitHub.
