How can I run a prover locally? And are there any requirements for 1TB memory?

To run a prover locally, you don't need 1TB of memory unless you're running production nodes. For local nodes, you can run it on your local machine without modifying the test.prover.config.json file. Follow the instructions provided in this guide for running the prover locally: https://github.com/0xPolygonHermez/zkevm-node/blob/develop/docs/running_local.md
