Isn't a apt install -y libtorch1.13 enough?

Can you add libtorch1.13 to the # Install runtime dependencies and tools line above, and try without this change here, if it works?

We have agreed to leave it as it is, since it will not be merged into develop and the following did not work:
-
apt install libtorch2.6gives build error:1.881 E: Unable to locate package libtorch2.6 1.881 E: Couldn't find any package by glob 'libtorch2.6' -
apt install libtorch1.13gives run error:/usr/local/bin/iota: error while loading shared libraries: libtorch_cpu.so: cannot open shared object file: No such file or directory -
apt install libtorch-devgives run error:/usr/local/bin/iota: symbol lookup error: /usr/local/bin/iota: undefined symbol: _ZNK3c107SymBool10guard_boolEPKcl

Note
This change is only needed for gas price prediction experiments, and the base branch of this PR is not planned to be merged to
develop.Description of change
This PR copies
libtorch(required by the gas price predictor) to theiota-toolsdocker image, in the same way how it is done for theiota-nodeimage.The
iota-toolsimage builds theiota-nodecomponent, which is then used indev-tools/iota-private-network/bootstrap.shto generate genesis. Running thedev-tools/iota-private-network/bootstrap.shscript results inif the
libtorchlibrary is not copied to theiota-toolsdocker image.EDIT:
How the change has been tested
Run these commands from the monorepo root folder:
