Frequently Asked Questions


How can I train the model on NimbleBox uninterruptedly?

With NimbleBox, it is easy to use train models uninterrupted. However, there are a few steps to take before training models on NimbleBox.

  • Ensure that you have an active internet connection.

  • The Dedicated Hardware is enabled.

  • You have chosen a sufficient amount of RAM.

  • When you run in a terminal, be sure to use the tmux command. Note: We recommend you save models intermittently. This allows you to restore the most recently saved version and resume training.

Do you share my models, data, and code without informing me?

No. We understand and respect your need for confidentiality in your models, data, and code. We care about our customers' privacy and data security. We do not share any of your data with others. So, we give you complete control over whom you can invite and share your instance.

Welcome to NimbleBox.You can use the lowest configuration CPU to upload data, code, and debug. This method can help reduce costs.We recommend preemptive projects if you train small models and do not mind restarting the computing instance and continuing work.If you are training large models for many hours, check the FAQ 'How can I train the model on NimbleBox uninterruptedly?'You can find further information on hardware configuration in the documentation. See this twitter thread to learn more on choosing the hardware
