* Revert "Revert "Support of scikit-learn with ray joblib backend (#6925)" (#6957)"
This reverts commit 86100bc119.
* adding scikit-learn to dependencies
* Add `RandomEnv` example to examples folder.
Convert warning into Error message when using an LSTM in a non-shared-vf network (after the warning, the program would crash).
* LINT.
* Fix issue #6884. LSTM + non-shared vf NN + PPO crashes when using a Tuple action space.
* LINT
* Change warning message for Model: shared_vf=False, LSTM=True cases.
* Bug fix.
* Add examples/random_env.py test to Jenkins.
* Remove all __future__ imports from RLlib.
* Remove (object) again from tf_run_builder.py::TFRunBuilder.
* Fix 2xLINT warnings.
* Fix broken appo_policy import (must be appo_tf_policy)
* Remove future imports from all other ray files (not just RLlib).
* Remove future imports from all other ray files (not just RLlib).
* Remove future import blocks that contain `unicode_literals` as well.
Revert appo_tf_policy.py to appo_policy.py (belongs to another PR).
* Add two empty lines before Schedule class.
* Put back __future__ imports into determine_tests_to_run.py. Fails otherwise on a py2/print related error.
* Unifying the code for PGTrainer/Policy wrt tf vs torch.
Adding loss function test cases for the PGAgent (confirm equivalence of tf and torch).
* Fix LINT line-len errors.
* Fix LINT errors.
* Fix `tf_pg_policy` imports (formerly: `pg_policy`).
* Rename tf_pg_... into pg_tf_... following <alg>_<framework>_... convention, where ...=policy/loss/agent/trainer.
Retire `PGAgent` class (use PGTrainer instead).
* - Move PG test into agents/pg/tests directory.
- All test cases will be located near the classes that are tested and
then built into the Bazel/Travis test suite.
* Moved post_process_advantages into pg.py (from pg_tf_policy.py), b/c
the function is not a tf-specific one.
* Fix remaining import errors for agents/pg/...
* Fix circular dependency in pg imports.
* Add pg tests to Jenkins test suite.
* [Dashboard] Add remaining features from old dashboard
* Fix linting errors
* Set cluster uptime statistic to N/A
* Use proper singular or plural words for workers column
* Ignore .js, .jsx, .ts, .tsx files in check-git-clang-format-output.sh
* Fix bash quote issue
* [Serve] Added deadline awareness
Added deadline awareness while enqueuing a query
Using Blist sorted-list implementation (ascending order) to get queries according to their specified deadlines. [buffer_queues]
Exposed slo_ms via handle/http request
Added slo example
The queries in example will be executed in almost the opposite order of which they are fired
Added slo pytest
Added check for slo_ms to not be negative
Included the changes suggested
* Linting Corrections
* Adding the code changes suggested by format.sh
* Added the suggested changes
Added justification for blist
Added blist in travis/ci/install-dependencies.sh
* Fixed linting issues
* Added blist to ray/doc/requirements-doc.txt
