This PR has the solution for HPU Graph issue reported in #130

[hsubramony]

@yafshar did you try the env variable

ENABLE_HPU_GRAPH | True/False | True | Enable hpu graph or not

also please retry the issue on latest docker 1.15.1 + #134

@yafshar did you try the env variable

ENABLE_HPU_GRAPH | True/False | True | Enable hpu graph or not

For workloads which have an issue, disabling the hpu graph by env variable works. But it has the performance effect.

also please retry the issue on latest docker 1.15.1 + #134
The issue exists there as well.

One point is that #134 uses the merge from tgi_gaudi:habana-main which has the dill patch for dill 0.3.7, we should update that to 0.3.8 to have the correct dependencies.
