Troubleshooting

​

Common solutions

1. Reconnect to the instance with ctrl + d and tnr connect <instance_id>
2. Upgrade tnr with pip install tnr --upgrade on your local machine
3. Restart the instance by running tnr stop <instance_id> and tnr start <instance_id>

​

Logs

To assist troubleshooting, the GCP/AWS instance logs for each instance are saved to the file /var/log/syslog

​

Common errors

​

Path or permissions issues (Common on Windows)

To avoid path and permissions issues, we recommend using Linux/WSL wherever possible. Otherwise, a few steps resolve most issues:

1. Install tnr with the --user flag, i.e. pip install tnr --user
2. Ensure your user scripts directory is added to path and restart your shell
3. If all else fails, run your shell as an administrator and $ pip install tnr

​

Function not implemented

A common error you may encounter is some variant of “This function is not implemented.” What this means is that your program touches a portion of the CUDA API that we do not currently support. If you encounter this, please contact us.

​

SSH errors

Sometimes, instances will encounter SSH-related errors, such as Error reading SSH protocol banner. To resolve these, restart your instance with tnr stop <instance_id> and tnr start <instance_id>
