Store (start_block, end_block) in each DHT record for reliability (#510) 
This PR fixes gaps in the DHT server info caused by unavailable DHT keys. Now, one DHT key is enough to get info about all blocks hosted by a server - so we'll see info until all keys are unavailable.

Also, this PR refactors `petals.client.routing` and `petals.server.block_selection` modules to use the common `compute_spans()` function (defined in `petals.utils.dht`) and `RemoteSpanInfo` class (defined in `petals.data_structures`).

Use get_logger(__name__) instead of get_logger(__file__) (#265) 1 year ago

Add `allowed_servers`, `max_retries` options to the client, improve logs (#235) 1 year ago

Don't switch blocks if it makes swarm disjoint (#210) 
Even if the swarm seems to have at least 2 servers for each block, turning off on one of the servers could break it. That's because once a server is turned off, others may move to a better position, creating a significant downtime on their way. This PR prohibits switching blocks if it would make the swarm disjoint along the way.

Optimize RemoteSequenceManager (#106) 
- [x] made RemoteSequenceManager into a background thread that pre-fetches information instead of running just in time
- [x] moved routing-related stuff to petals.client.routing
- [x] extract remote peer routing information to RemoteSequenceInfo
- [x] made sure that the code survives continued use (e.g. one hour)
- [x] updated every spot where update_ is called manually
- [x] modified get_sequence to check that the thread is alive, warn if not
- [x] removed max_retries, switched rpc_info to exponential backoff
- [x] fixed a bg that causes RemoteSeq* to lose user-defined hyperparameters (e.g. timeout) upon subsequencing (sequential[3:5])
- [x] moved client-side points strategy to client.routing
- [x] ensured that RemoteSequenceManager thread created in get_remote_module properly shuts down when the module is destroyed
- [x] resolved minor affected todos
- [x] modified tests to no longer use PYTHONPATH
- [x] worked around protocol error in rpc_info

Make Petals a pip-installable package (attempt 2) (#102) 
1. Petals can be now installed using `pip install git+https://github.com/bigscience-workshop/petals`
    - In case if you already cloned the repo, you can do `pip install .` or `pip install .[dev]`
2. Moved `src` => `src/petals`
    - Replaced `from src.smth import smth` with `from petals.smth import smth`
3. Moved `cli` => `src/petals/cli`
    - Replaced `python -m cli.run_smth` with `python -m petals.cli.run_smth` (all utilities are now available right after pip installation)
4. Moved the `requirements*.txt` contents to `setup.cfg` (`requirements.txt` for packages is not supported well by modern packaging utils)
5. Increased the package version from `0.2` to `1.0alpha1`
