Autotuning with small storage space

Hi,

I am tuning a model on a device with tiny amount of storage space left, and when tuning a big model at some point I get an error because there is no more space left.
At some point in the autotuning process, I am seeing several tvm modules on the device (generated during the same autotuning process), do you have an idea of why does this happen? Can I remove some of them? If so, which ones?
