I'm using a python code with the traci library to know if there are any vehicles near a certain distance to a chosen vehicle, to test a solution I'm trying to implement I need to know a vehicle's current edge.
I'm on Ubuntu 18.04.3 LTS, using sublime to edit the code and the os, sys, optparse, subprocess, random, math libraries. I've tried using getLaneId and getEdgeId, the last one is not in the documentation but I tough I've seen it somewhere and tried to test it.
. Another option that i had was using getNeighbors but i didn't know exactly how to use it and it returned the same error message as the previous commands.
def run():
step = 0
while traci.simulation.getMinExpectedNumber() > 0:
traci.simulationStep()
print(step)
print(distancia("veh1","veh0"))
step += 1
if step > 2:
print(traci.vehicle.getLaneId("veh0"))
traci.close()
sys.stdout.flush()
All of them returned the following error message : AttributeError: VehicleDomain instance has no attribute 'getLaneId'. But I think the vehicle domain has indeed the getLaneId attribute since it is in the documentation: https://sumo.dlr.de/pydoc/traci._vehicle.html#VehicleDomain-getSpeed.
I was expecting it to return the edge's id. Please I need help with this problem. Thank you in advance.
The TraCI command for edgeID can be found in the _vehicle.VehicleDomain module. The syntax is as follows:
traci._vehicle.VehicleDomain.getRoadID(self, vehicleID)
It needs to be getLaneID with a capital D.

I have 2 places running the same linting job:
Machine 1: Ubuntu over SSH
pandas==1.2.3
pylint==2.7.4
python 3.8.10
Machine 2: Gitlab CI Docker image, python:3.8.12-buster
pandas==1.2.3
pylint==2.7.4
Python 3.8.12
The Ubuntu machine is able to lint all the code fine, and it has for many months. Same for the CI job, except it had been running Python 3.7.8. Now that I upgraded the Docker image to Python 3.8.12, it throws several no-member linting errors on some Pandas objects. I've tried clearing CI caches etc.
I wish I could provide something more reproducible. But, to check my understanding of what a linter is doing, is it theoretically possible that a small version difference in python messes up pylint like this? For something like a no-member error on Pandas objects, I would think the dominant factor is the pandas version, but those are equal, so I'm confused!
Update:
I've looked at the Pandas code for pd.read_sql_query, which is what's causing the no-member error. It says:
def read_sql_query(
sql,
con,
index_col=None,
coerce_float=True,
params=None,
parse_dates=None,
chunksize: Optional[int] = None,
) -> Union[DataFrame, Iterator[DataFrame]]:
In Docker, I get E1101: Generator 'generator' has no 'query' member (no-member) (because I'm running .query on the returned dataframe). So it seems Pylint thinks that this function returns a generator. But it does not make this assumption in my other setup. (I've also verified the SHA sum of pandas/io/sql.py matches). This seems similar to this issue, but I am still baffled by the discrepancy in environments.
A fix that worked was to bump a limit like:
init-hook = "import astroid; astroid.context.InferenceContext.max_inferred = 500"
in my .pylintrc file, as explained here.
I'm unsure why/if this is connected to my change in Python version, but I'm happy to use this and move on for now. It's probably complex.
(Another hack was to write a function that returns the passed arg if the passed arg is a dataframe, and returns 1 dataframe if the passed arg is an iterable of dataframes. So the ambiguous-type object could be passed through this wrapper to clarify things for Pylint. While this was more intrusive on our codebase, we had dozens of calls to pd.read_csv and pd.real_sql_query, and only about 3 calls caused confusion for Pylint, so we almost used this solution)
I'm making a program that makes the cars running in the simulation pass on their colors to other cars, to achieve that I'm using the TraCi function 'getColor'. The problem is that every car that I ask the color returns (255,255,0,255) doesn't matter what the actual color is. However, using 'getColor' inside a condition for the "contamination" makes the program work, maybe out of sheer luck. Please help me understand how to fix it and how it works.
I'm on Ubuntu 18.04.3 LTS, SUMO 0.32.0 and using the traci library. I've tried modifying the program and running the simulation step by step, even running the same line in different code with the same idea in mind.
This is the program in which the "contamination" works although it gets the wrong colors:
def run():
step = 0
while traci.simulation.getMinExpectedNumber() > 0:
traci.simulationStep()
step += 1
if step > 2:
if distancia("veh1","veh0") < 5:
traci.vehicle.setColor("veh1",(255,0,0,255))
if distancia("veh0","veh2") < 5 :
traci.vehicle.setColor("veh2",(255,0,0,255))
if traci.vehicle.getColor("veh2") == (255,0,0,255):
if distancia("veh1","veh2") < 5 :
traci.vehicle.setColor("veh1",(255,0,0,255))
print(traci.vehicle.getColor("veh1"))
traci.close()
sys.stdout.flush()
I hoped when I selected the red car I would get (255,0,0,255), but I got (255,255,0,0). But it doesn't get any error messages, just shows the worng color.
It seems that the default color for traci is yellow, I'd to set every car to its own color from the python code to start doing what I wanted.
I run ASR experiment using Kaldi on SGE cluster consisting of two workstation with TITAN XP.
And randomly I meet the following problem:
ERROR (nnet3-train[5.2.62~4-a2342]:FinalizeActiveGpu():cu-device.cc:217) cudaError_t 1 : "__global__ function call is not configured" returned from 'cublasCreate(&handle_)'
I guess something is wrong with GPU driver or hardware.
Could you please offer some help?
And here is the complete log
I had similar issue in running darknet in one of the TX2
with reference to
https://blog.csdn.net/JIEJINQUANIL/article/details/103091537
enter the root by
sudo su
Then source the catkin_ws
Then launch the darkent.
Then can run.
Here is my result
Hope you can solve it by similar method
Im trying to call a command from wsadminlib.py to change the initialHeapSize and the maximumHeapSize in a script. But unfortunately my jython (and general scripting knowledge) is still total newbie.
Im using the call
#Change Java Heap Size
setJvmProperty(nodeName,serverName,maximumHeapsize -2048 ,initialHeapSize -2048)
Which should relate to the command in the wsadminlib.py library
def setJvmProperty(nodename,servername,propertyname,value):
"""Set a particular JVM property for the named server
Some useful examples:
'maximumHeapSize': 512 ,
'initialHeapSize':512,
'verboseModeGarbageCollection':"true",
'genericJvmArguments':"-Xgcpolicy:gencon -Xdump:heap:events=user -Xgc:noAdaptiveTenure,tenureAge=8,stdGlobalCompactToSatisfyAllocate -Xconcurrentlevel1 -Xtgc:parallel",
"""
jvm = getServerJvm(nodename,servername)
AdminConfig.modify(jvm, [[propertyname, value]])
But I'm met with this issue when i run the script
WASX7017E: Exception received while running file "/etc/was-scripts/administrateservertest.py"; exception information: com.ibm.bsf.BSFException: exception from Jython:
Traceback (innermost last):
File "", line 14, in ?
NameError: maximumHeapsize
Any suggestions would be appreciated as I'm tearing my hair out trying to work this out
this was answered by a friend on face book
I think you might need to make two calls, one for each property you
want to set. e.g.
setJvmProperty(nodeName,serverName,'maximumHeapsize',2048)
For others looking for a more specific answer, try this:
AdminConfig.modify(jvmId,[['genericJvmArguments',arguments],["maximumHeapSize", str(1536)]])
I need to capture the output of the below to a variable.
I know we can get to serverRuntime or domainRuntime() trees and get the state. But need to get the below working.
wls:/owb/serverConfig> state('Server1')
Current state of 'Server1' : RUNNING
I tried two ways:
wls:/owb/serverConfig> print state('Server1')
Current state of 'Server1' : RUNNING
None
wls:/owb/serverConfig> x=state('Server1')
Current state of 'Server1' : RUNNING
wls:/owb/serverConfig> print x
None
You have to use the getState() method of server runtime mbean.
You can obtain the server runtime mbean by navigating into wlst runtime tree or by using a lookup method.
Sample:
domainRuntime()
slrBean = cmo.lookupServerLifeCycleRuntime('Server1')
status = slrBean.getState()
print 'Status of Managed Server is '+status
See also Getting Runtime Information in WLST official documentation.
This same question was raised by Dianyuan Wang with me 2011.
Here is the steps to resolve your issue.
1. Capture the output of state command using redirect, stopRedirect command
2. Use the Python regular expression in search function to extract the desired server output.
Code snippet is here
fileName='/tmp/myserver_state.txt'
redirect(fileName)
state(server_nm,'Server')
stopRedirect()
f = open(fileName)
try:
for line in f.readlines():
if re.search('Current state',line):
status[server_nm]=line
except:
continue
Now you can apply desired logic after this block.
Cheers!!
HTH
Here is what I am using and is working like charm
cd("/ServerRuntimes/ms1")
state=cmo.getState()
print state
