TI-ONE Platform FAQ: Managing Notebook Instances, Switching Resources, and Resolving Common Issues

During the live broadcast on May 11, Tencent Cloud engineers presented best practices for the TI-ONE competition platform and answered participants' questions, which are compiled here as a concise FAQ.

Q1: After creating a TI‑Notebook instance and running ./init.sh run , the baseline conda environment and Jupyter kernel become incorrect after a restart. Solution: The system disk is cleared on stop; use the provided ./run.sh fix script to restore the environment (see the script for details).

Q2: How to switch a notebook instance from CPU to GPU resources and retain data? Solution: In the TI‑ONE Notebook management page, stop the running instance, click Edit , and change the hardware type (CPU ↔ GPU), adjust data‑disk size, lifecycle scripts, and other settings. Data on the data disk persists.

Q3: Where are the competition data and baseline code located, and why does a “Read‑only file system” error appear? Solution: Both the dataset and baseline code reside on a read‑only shared disk mounted at /home/tione/notebook/algo-2021/ . The read‑only nature requires participants to copy data and code to their writable data disk after instance startup, which typically takes about one hour. Example copy commands: time cp -r -d /home/tione/notebook/algo-2021/baseline/dataset /home/tione/notebook/ time cp -r -d /home/tione/notebook/algo-2021/baseline/structuring/* /home/tione/notebook/

Q4: Why does mmcv installation fail when running ./init.sh run for Track 1? Solution: The failure is due to a missing trusted host. Install with: pip install mmcv==1.0.3 -i http://mirrors.tencentyun.com/pypi/simple --trusted-host mirrors.tencentyun.com The script has been updated; using the latest ./init.sh run resolves the issue.

Q5: How to add a Git repository to the notebook, and why does configuration fail during creation? Solution: Pulling a Git repository can time out; it is recommended not to configure Git at instance creation. After the instance is ready, use the Notebook’s built‑in Git plugin to clone or manage repositories.
