Failed to run examples/sumo/sugiyama.py

I followed the steps for the installation procedure (https://berkeleyflow.readthedocs.io/en/latest/flow_setup.html). However, when i tried to run the example ( in the "Testing the Installation" section) I get the following error:

Traceback (most recent call last): File "examples/sumo/sugiyama.py", line 11, in from flow.envs.loop.loop_accel import AccelEnv, ADDITIONAL_ENV_PARAMS File "/home/dkoutras/flow/flow/envs/init.py", line 4, in from flow.envs.multiagent_env import MultiEnv File "/home/dkoutras/flow/flow/envs/multiagent_env.py", line 10, in from ray.rllib.env import MultiAgentEnv ModuleNotFoundError: No module named 'ray'

I have not installed the ray library, but as mentioned in the corresponding section I sould not need it anyway. Any ideas ?

Increasing the number of vehicles in Figure Eight scenario
Choose an option This is a:

[x] Question

[x] Feature request

Describe the issue Figure eight scenario only accommodates a maximum of 14 vehicles in Flow. Even if I give more than this, it is not effective. But I am planning to extend this to 100 vehicles involving RL and human vehicles. I just want to know the reason behind this limitation to be able to apply in a real world scenario. Can I add another route with this and expand the capacity_ Like merging one figure eight and one ring wave scenario or merging two figure eight scenarios to increase its capacity.

Expected behavior Many vehicles in a single road track

Desktop (please complete the following information):

OS: Ubuntu 18.04

Better folder structure and file names

Pull request information

Status: In development
Kind of changes: File and class names of environments/scenarios, structure of example folders
Related PR or issue: #564

Description

This PR introduces major changes to file names and folder structures, as well as fo some class names, mainly for the following folders:

envs
multiagent_envs (now is a subfolder under envs)
scenarios
examples
removal of cooperative_merge (and loop_merge)

TODO:

[x] better names for environments --> NL
[x] merge multiagent_envs into envs --> AY
[x] better name for scenarios so that they match the environments --> AY
[x] better file names (e.g. sugiyama, loop,ring -> ring) --> AY, NL

This is how the new envs folder looks like (some classes names have also been changed):

Having both RL and actuated traffic lights in a simple grid scenario
[QUESTION] Hello! I am trying to create a simple grid scenario containing at the same time actuated traffic lights and a group of RL-based traffic lights. I am modifying the following scripts:

flow/examples/rllib/green_wave.py (Experiment)

flow/scenatios/grid.py (Scenario)

flow/envs/green_wave_env.py (Environment)

According to the ADDITIONAL_ENV_PARAMS variable, either all traffic lights are "controlled" (RL) or either they are all actuated. I've tried to add every TL manually in the grid scenario but it seems that in the end the ADDITIONAL_ENV_PARAMS variable is who determines how traffic lights are managed in the simulation. Is there a way I could do this? I didn't find any documentation about it.

Thank you very much!

To fix this you could try to:

loosen the range of package versions you've specified

remove package versions to allow pip attempt to solve the dependency conflict

Update requirements.txt and environment.yml

Bug Description

It is impossible to create an environment or install the proper dependencies for Flow to work, with the current environment.yml and requirements.txt. This is because the dependencies are mostly outdated and have conflicts, which need to be resolved during installation.

I personally had a hard time before I could actually get Flow to work on my Ubuntu 18.04 machine, so I'm posting the changes that MIGHT work for you as well (this totally depends on your machine as I have not tested it on any other OS).

environment.yml:

name: flow

dependencies:
    - python==3.7.3
    - pip:
        - scipy==1.1.0
        - lxml==4.4.1

If you still have some dependency issues, just make sure that you remove the versions from the above files and allow pip to resolve any conflicts. Another tip is to uninstall and reinstall packages if they throw ImportError, ModuleNotFoundError etc.

Also, any help regarding how to install Flow on Windows would be greatly appreciated.

Bump joblib from 0.10.3 to 1.2.0
Bumps joblib from 0.10.3 to 1.2.0.

Changelog

Sourced from joblib's changelog.

Release 1.2.0

Fix a security issue where eval(pre_dispatch) could potentially run arbitrary code. Now only basic numerics are supported. joblib/joblib#1327

Make sure that joblib works even when multiprocessing is not available, for instance with Pyodide joblib/joblib#1256

Avoid unnecessary warnings when workers and main process delete the temporary memmap folder contents concurrently. joblib/joblib#1263

Fix memory alignment bug for pickles containing numpy arrays. This is especially important when loading the pickle with mmap_mode != None as the resulting numpy.memmap object would not be able to correct the misalignment without performing a memory copy. This bug would cause invalid computation and segmentation faults with native code that would directly access the underlying data buffer of a numpy array, for instance C/C++/Cython code compiled with older GCC versions or some old OpenBLAS written in platform specific assembly. joblib/joblib#1254

Vendor cloudpickle 2.2.0 which adds support for PyPy 3.8+.

Vendor loky 3.3.0 which fixes several bugs including:

robustly forcibly terminating worker processes in case of a crash (joblib/joblib#1269);

avoiding leaking worker processes in case of nested loky parallel calls;

reliability spawn the correct number of reusable workers.

Release 1.1.0

Fix byte order inconsistency issue during deserialization using joblib.load in cross-endian environment: the numpy arrays are now always loaded to use the system byte order, independently of the byte order of the system that serialized the pickle. joblib/joblib#1181

Fix joblib.Memory bug with the ignore parameter when the cached function is a decorated function.

Retrieving datas from SUMO simulation started with flow using TraCI from another terminal

I am using Flow to start a SUMO simulation integrating deep reinforcement learning inside the process. I am also using another computer to retrieve some data from the simulation using TraCI.

The first problem is that flow does not assign the port I choose correctly. Secondly, the other computer connects to the SUMO simulation using TraCI, but as soon as it starts it goes out and doesn't save anything. The simulation keeps going on on the other computer.

• THIS IS THE CODE I USE ON THE FIRST COMPUTER TO ASSIGN THE PORT AND THE CLIENTS FOR SUMO

sim_params = SumoParams(port=45678, render=VISUALIZE_SIM_IN_SUMO, sim_step=1, num_clients=2)

• THIS IS THE CODE I USE ON THE SECOND COMPUTER TO CONNECT WITH TRACI AND RETRIEVE DATA

PORT = 49745 ( I need to set it once I start the simulation on the first computer since Flow does not use the port I specified at the beginning)

traci.init(PORT,tc.DEFAULT_NUM_RETRIES,"second_computer.local") traci.setOrder(2) # number can be anything as long as each client gets its number

If this solution is not achievable, do you know how to get this data from another terminal ?

Bump lxml from 4.4.1 to 4.9.1
Bumps lxml from 4.4.1 to 4.9.1.

Changelog

Sourced from lxml's changelog.

4.9.1 (2022-07-01)

Bugs fixed

A crash was resolved when using iterwalk() (or canonicalize()) after parsing certain incorrect input. Note that iterwalk() can crash on valid input parsed with the same parser after failing to parse the incorrect input.

4.9.0 (2022-06-01)

Bugs fixed

GH#341: The mixin inheritance order in lxml.html was corrected. Patch by xmo-odoo.

Other changes

Built with Cython 0.29.30 to adapt to changes in Python 3.11 and 3.12.

Wheels include zlib 1.2.12, libxml2 2.9.14 and libxslt 1.1.35 (libxml2 2.9.12+ and libxslt 1.1.34 on Windows).

GH#343: Windows-AArch64 build support in Visual Studio. Patch by Steve Dower.

4.8.0 (2022-02-17)

Features added

GH#337: Path-like objects are now supported throughout the API instead of just strings. Patch by Henning Janssen.

The ElementMaker now supports QName values as tags, which always override the default namespace of the factory.

Bugs fixed

GH#338: In lxml.objectify, the XSI float annotation "nan" and "inf" were spelled in lower case, whereas XML Schema datatypes define them as "NaN" and "INF" respectively.

Bump numpy from 1.18.4 to 1.22.0
Bumps numpy from 1.18.4 to 1.22.0.

Release notes

Sourced from numpy's releases.

v1.22.0

NumPy 1.22.0 Release Notes

NumPy 1.22.0 is a big release featuring the work of 153 contributors spread over 609 pull requests. There have been many improvements, highlights are:

Annotations of the main namespace are essentially complete. Upstream is a moving target, so there will likely be further improvements, but the major work is done. This is probably the most user visible enhancement in this release.

A preliminary version of the proposed Array-API is provided. This is a step in creating a standard collection of functions that can be used across application such as CuPy and JAX.

NumPy now has a DLPack backend. DLPack provides a common interchange format for array (tensor) data.

New methods for quantile, percentile, and related functions. The new methods provide a complete set of the methods commonly found in the literature.

A new configurable allocator for use by downstream projects.

These are in addition to the ongoing work to provide SIMD support for commonly used functions, improvements to F2PY, and better documentation.

The Python versions supported in this release are 3.8-3.10, Python 3.7 has been dropped. Note that 32 bit wheels are only provided for Python 3.8 and 3.9 on Windows, all other wheels are 64 bits on account of Ubuntu, Fedora, and other Linux distributions dropping 32 bit support. All 64 bit wheels are also linked with 64 bit integer OpenBLAS, which should fix the occasional problems encountered by folks using truly huge arrays.

Expired deprecations

Deprecated numeric style dtype strings have been removed

Using the strings "Bytes0", "Datetime64", "Str0", "Uint32", and "Uint64" as a dtype will now raise a TypeError.

(gh-19539)

Expired deprecations for loads, ndfromtxt, and mafromtxt in npyio

numpy.loads was deprecated in v1.15, with the recommendation that users use pickle.loads instead. ndfromtxt and mafromtxt were both deprecated in v1.17 - users should use numpy.genfromtxt instead with the appropriate value for the usemask parameter.
