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'm trying to get a BG95 to activate on hologram.
Here are my commands:
AT+QCFG="band",F,180A,180A OK
AT+QCFG="iotopmode",2 OK
AT+QCFG="nwscanseq",020301 OK
AT+QCFG="nwscanmode",0 OK
AT+QCFG="snrscan",0 OK
AT+QICSGP=1,1,"hologram","","",1 OK
AT+QIACT=1 ERROR
At first I thought it was antenna/signal related so I ran AT+CSQ and got this:
+csq: 11,99
This tells me I have a good signal I believe.
Next I tried AT+QNWINFO and get this:
+QNWINFO: "eMTC","311480","LTE BAND 13",5230
In my mind this is saying it's connected to a network.
After trying that I tried to activate again and got this:
AT+QIACT=1
ERROR
The weird thing is it activated just fine about a week ago with pure AT commands. I did try and use an Arduino library with it (WisLTEBG96TCPIP) which may have changed a setting in it. I've done a factory reset but the it still woln't activate.
Another strange thing is the hologram dashboard. Every once and a while it will show the SIM as connected, even though I can't activate.
I have tried with 2 different SIM cards any get the same activation error.
Any help would be greatly appreciated!
Verizon has cut off all non ODI products. If your hardware has not been Verizon ODI 'certified' it will no longer be allow to be connected to their network, I have 5 new pet rocks thanks to them. The solution is to purchase new modems from vendors that have been through the Verizon ODI program or switch carriers.
I had the same problem before, after a lot of maling with network operator I find out that there isn't a LTE-CAT-M1 (eMTC) network in my area, I tested in another area successfully
Also before setting AT+QCFG commands try AT+CFUN = 0
and after setting AT+QCFG commands try AT+CFUN = 1 .
before sending AT+QIACT, try 'AT+CEREG?' command several times and tell me what is the return of it
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 would like to know how to print the solve progress using CbcSolver?
I already used the log level parameter:
m = Model(solver = CbcSolver(log=1))
it works and you can choose between 0 to 3, higher more details.
but my problem is that the log level only prints after the solver finish, i already put the the time limit parameter "sec" but when it is set for higher values never stops and i don't know why!!
m = Model(solver = CbcSolver(sec=90,log=1))
I was going to try callbacks but Cbc does not support callback.
I am positive that there is a way to print because when i use the opensolver in excel a set Cbc to solve it shows the progress.I just dont know how to do this!!
I have just started learning tensorflow, and wrote the following piece of code in Jupyter-Notebook :
a = tf.placeholder(tf.float32,shape=[3,3],name='X')
b = tf.constant([[5,5,5],[2,3,4],[4,5,6]],tf.float32,name='Y')
c = tf.matmul(a,b)
with tf.Session() as sess:
writer = tf.summary.FileWriter('./graphs',sess.graph)
print (sess.run(c,feed_dict={a:[[2,3,4],[4,5,6],[6,7,8]]}))
writer.close()
Running the tensorboard first time, gives a single X,Y and mult node as follows :
However, when I again compile my code (ctrl+enter), the tensorboard now makes a duplicate of the original graph.
I tried to resolve this( remove the older,dead nodes) by:
1. Deleting the event files.
2. Deleting the whole directory containing multiple event files of the same code.
3. Running fuser 6006/tcp -k before the tensorboard command line call.
But even after that, when I ran tensorboard, it would show the duplicate copies.
The only solution that worked was to reset the graph using tf.reset_default_graph() at the beginning of the code or to shut the notebook down and restart it.
My question is :
1. Why is it that even after deleting the event files, the older dead nodes keep showing up on the tensorboard ?. And yes I even restarted Tensorboard after each try, but duplicates were still there.
2. What are the ways if any, besides the two I listed above, to get rid of the dead nodes ?
The nodes you described are not dead. They are still exist and can be used.
When you run your code the first time, the nodes where created and added to the graph. When you execute the same cell for the second time, they are added one more time with the different names.
The same can be achieved if you will just copy twice the code in your .py file.
Your solution with tf.reset_default_graph() is the right one. Restarting the notebook works because all the information from the memory was removed. The same as rerunning .py file.
Your stuff with removing the even files does not work because nonetheless the files are removed, the nodes added to the graph in the memory are still there.
I was also having the same problem of tensorboard displaying duplicate graphs. I tried several measures like deleting the event files , deleting the log directory which contained the event files, but tensorboard would still remember the nodes and the graph from the previous run and show them as duplicate copies, one after another.
I noticed each time I ran the code tensorflow would create the same nodes but with different names, which means it was still keeping the old nodes in its memory. Looked something like this in the python execution window:
After first run:
After running the code 2nd and 3rd time:
This solved the problem
1) Restarting the kernel before each run solved the problem
2) As mentioned in above posts, adding tf.reset_default_graph() in the beginning of the code also solved the problem.
In normal applescript, the script is executed down the page, and so any code in loops for every 5 seconds will only run while the loop is running - there is no way to have a single function run every few second regardless of what the script is currently doing or where it is in the script (that I know of). In cocoa-applescript, however, is there a way to run a handler every 5 seconds, at all times, no matter what it is currently doing? Here is what it should be doing in my cocoa-applescript app:
on checkInternetStrength()
do shell script "/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I | grep 'agrCtlRSSI:'" -- this being the script which returns the line containing the signal strength
set SignalStrength to result
set RSSIcount to (count of characters in SignalStrength)
set SignalStrength to ((characters 18 thru RSSIcount of SignalStrength) as string) as integer -- this to turn SignalStrength into just the number and not the whole output line
set SignalStrength to (100 + SignalStrength) as integer
set SignalBar's setIntValue_(SignalStrength) -- SignalBar being the Level Indicator described below
end checkInternetStrength
Summed up, it runs the airport command to check internet connection, turns this into a number from 1 to 100 and uses this on an NSLevelIndicator (100 maximum) to show current signal strength graphically. Now, there is no point having this run once or when you hit a button - that is an option, but it would be nice if it updated itself every, say, 5 seconds with the realtime value. So is there any way to have a process which runs every 5 seconds to do this, while still enabling full functionality of the rest of the script and interface - i.e. as a background process? Comment if you need more extracts from the script.
Example
In Unity-C# scripting, the 'void Update() {code}' will run the code within it every frame while doing everything else simultaneously, so a cocoa-applescript version of this might be an answer, if anyone knows.
I Dont believe this is possible but what I had a similar problem before, what i do, I have an external applescript applicaion that is hidden the repeats the commands, the only problem is, it wont send it back to the app, you'll have to make the external applescript app do it, like
display notification, etc..., in the applescript apps "Info.plist" you can add this:
<key>LSUIElement</key>
<string>1</string>
To make the app run invisibly, but sorry i dont think you can run a handler in the app its self
