I'm using Colab Pro and I have no issue with the RAM when I'm using either GPU or TPU. The only problem is that my running usually takes more than 12 hours and it looks like Colab automatically stops (with no error) after 12 hours. I've reached out to their support and got no response (this is strange enough for itself that how/why Google does not have proper support for paid Colab Pro technical, not billing, issues!) I wonder if there is any way that the runtime limit can be increased to more than 12 hours? Or, has anyone experienced a similar situation or has any contact I can reach out?
A similar situation is described here, but since there was no question asked, I'm creating this post.
