FileNotFoundError when running sugiyama.py

ZhuangDingyi commented 5 years ago

Hi, I really appreciate your work. I followed the steps and was ready to run sugiyama.py but got the Error:

Error during start: Traceback (most recent call last): File "/home/dingyi/flow-project/flow/flow/scenarios/base_scenario.py", line 827, in generate_net edges_dict, conn_dict = self._import_edges_from_net() File "/home/dingyi/flow-project/flow/flow/scenarios/base_scenario.py", line 1216, in _import_edges_from_net os.path.join(self.cfg_path, self.netfn), parser=parser) File "/home/dingyi/anaconda3/envs/flow/lib/python3.5/xml/etree/ElementTree.py", line 1184, in parse tree.parse(source, parser) File "/home/dingyi/anaconda3/envs/flow/lib/python3.5/xml/etree/ElementTree.py", line 585, in parse source = open(source, "rb") FileNotFoundError: [Errno 2] No such file or directory: '/home/dingyi/flow-project/flow/flow/scenarios/debug/cfg/sugiyama_20181220-1150491545277849.601907.net.xml'

I have noticed that 2018/12/20-11:50 is exactly the time I run the command. Is there any code that request real-time net.xml files from some external sources?

eugenevinitsky commented 5 years ago

Hi @ZhuangDingyi, sorry to hear this! It looks to me like sumo isn't installed properly; did you install from source or from the binaries (i.e. as in https://flow.readthedocs.io/en/latest/flow_setup.html#e-easy-install-sumo-optional)? If you didn't do the latter, try it! It may resolve your problem.

ZhuangDingyi commented 5 years ago

Thanks @eugenevinitsky and sorry for a late update. I tried to install sumo in another way and it did fix the problem. But now I encountered other problems when running examples (SUMO GUI has successfully opened):

Error: tcpip::Socket::recvAndCheck @ recv: peer shutdown

I found that tcpip problems appear frequently in SUMO. Do you have any idea about it? Thank you again for your kind response!

eugenevinitsky commented 5 years ago

Hi @ZhuangDingyi, This is an error message that SUMO prints that we have not yet been able to get rid of but does not seem to actually impede any of our run scripts. Does the simulation actually run?

ZhuangDingyi commented 5 years ago

Hi @eugenevinitsky, Actually, the simulation just got stuck in the first place when I clicked "run" button. The error message jumped out and the terminal started retrying over and over again. I think I need to focused on the SUMO issue in the following days. If I have any updates, I will let you know. Thanks again for your kind response and merry the upcoming Christmas :P

eugenevinitsky commented 5 years ago

Hi @ZhuangDingyi, oh can you post the whole error message? We should be able to help you. Merry upcoming Christmas!

ZhuangDingyi commented 5 years ago

Of course @eugenevinitsky ,here are the codes and results:

Then I run (flow) dingyi@DingyiZhuang:~/flow-project/flow/tutorials$ python ~/flow-project/flow/examples/sumo/sugiyama.py

I got the result in terminal (no retrying this time):

    vehicle_obs = self.traci_connection.vehicle.getSubscriptionResults()
TypeError: getSubscriptionResults() missing 1 required positional argument: 'objectID'

Of course, in the SUMO-GUI I got

Error: tcpip::Socket::recvAndCheck @ recv: peer shutdown
Quitting (on error).

But it is glad that the vehicles are arranged in the loop. I might mistake some previous errors where terminal is retrying over and over again. I have update some packages last night and fixed some environment issues (maybe?) and now only this TypeError occurs. Thanks very much for your warm help and wishes:)

eugenevinitsky commented 5 years ago

@ZhuangDingyi I see! It looks like your Traci version doesn't match your SUMO version. My recommendation, if you are running this in a conda env, go to the main folder and run python setup.py develop. Then, check your .bash_rc, or .bash_profile if you are running a mac and make sure that there are no extraneous definitions defining a path to TRACI such as PYTHONPATH="$HOME/sumo/tools:$PYTHONPATH

Again, sorry for the trouble. We are working hard to make the install process easier.

AboudyKreidieh commented 5 years ago

closing this issue since it's gone stale. feel free to reopen if this is still an issue

But it is fine when using Terminal to run the code. I have no idea why this occurs.......

Thank you!

AboudyKreidieh commented 5 years ago

Hi @yurunsheng1 sorry for the late reply! My best guess is pycharm is having difficulty finding the sumo binaries, hence the error message:

/bin/sh: 1: netconvert: not found

You may want to look into this online, there may be suggestions about how to mix it.

buechelmartin commented 5 years ago

Hi @yurunsheng1,

just had the same issue with Pycharm giving the FileNotFoundError while in the terminal everything worked fine. The problem was, as @AboudyKreidieh pointed out, that the binaries of Sumo could not be found within PyCharm.

The Sumo path was added to the bashrc file by the sumo installation script, but Pycharm does not load this, unlike the terminal. Other than expected, starting PyCharm from the console also did not help. Since I could not just append the sumo path within PyCharm as done by the export command, my solution was as follows:

add the PATH environment variable in the Run/Debug configuration of Pycharm.
paste the FULL paths string to the value field of the PATH environment variable.

To get the full path string my approach was to:

add these lines on top of the main python file: import os print(os.environ['PATH'])
run this file from the conda env in the terminal
copy the print output from the terminal

Might not be the most beautiful solution, but now it works.

yurunsheng1 commented 5 years ago

I will have a try, thank you so much! @buechelmartin @eugenevinitsky @AboudyKreidieh

buechelmartin commented 5 years ago

If you initial motivation of using Pycharm was to be able to use the debugger, you might want to know that I wasn't successful yet in using it within the environment python code. Seems like the way Ray is calling it's workers isn't supported by the Pycharm debugger, at least unless you are using the Professional version. I could not verify this finding for sure though.

Being aware that this might be a new issue, I want to ask the others about hints how they manage to use a debugger working inside the environment code?

Since someone encountering the original error messages when using Pycharm might be highly interested to know if they really want to spend (or lose?) time fixing their Pycharm project, I post it here.

Hi @AboudyKreidieh, I tried sumo-gui successfully but encountered problems with when trying the example. Can you provide any insights? Thanks

@zhouhao0605: looks like your sumo path is not in your python path and you dont call the full, correct path.

@xiaoToby : check out the tutorial about visualization. per default, sumo is not rendered since this takes too long during training. you can run the visualizer from the checkpoints later. thats all in the tutorials
