"Can not receive a response from server, timeout after 5.00 seconds" after client.connect() about unrealcv

[qiuwch]

Did you check the server with vget /unrealcv/status make sure it shows "is listening"?

[ahtsan]

Yes, it shows "Is listening" and "Client connected"

[qiuwch]

What is your operating system and python version?
You are using UE4.12 and UnrealCV 0.3.9, right?

[ahtsan]

Yes, python 2.7.12 with Anaconda 4.1.1

[qiuwch]

Sounds like a problem related to #64.
v0.3.9 is not tested in UE4.12, it might be an issue related to that. I will verify this with UE4.12 and get back to you.

[ahtsan]

which version of UE is most stable? I switch from UE4.13 to 4.12 because it is stated that 4.12 is better. Thanks.

[qiuwch]

As reported in #68, there are some inconsistency in our documents. I will take the UE4.12 version down very soon. The docs.unrealcv.org is the latest version. Please use 4.14 if you can switch.

I am using UE 4.16 and unrealcv v.3.10 (compiled windows binaries that are provided in the release). I am not able to figure out why I am getting this ERROR for every command I try even for client.request('vget /unrealcv/status'), I get this:
ERROR:init:336:Can not receive a response from server, timeout after 5.00 seconds

Anyone knows any way around for this problem?

Hi @praveen96

Did you call client.connect() before trying to use client.request()?

If you use vget /unrealcv/status in the built-in terminal. Did the status showing it is Listening?

[praveen96]

In unreal command console,
vget /unrealcv/status shows it's listening, and also tried a few other commands which seem to work

when I try to unreal via python code, none of the commands are working
Yes, I did call clent.call() at the start and the message that prints is:
INFO:init:211:Got connection confirm: 'name of project'
Then for all the subsequent commands I try in that code give the time out error.

@qiuwch it shows me that it is not listening, what should i do?

I am following the Getting Started page on the UnrealCV website using RealisticRenderings. While attempting to run the snippet of python code given to generate images from the scene, I am running into the same timeout error (ERROR:init:336:Can not receive a response from server, timeout after 5.00 seconds).

In the unreal command console vget /unrealcv/status shows that it is listening and client.request('vget /unrealcv/status') prints 'Is Listening' and 'Client Connected'. I also receive a print line stating, INFO:init:211:Got connection confirm: 'connected to RealisticRendering', however, any subsequent commands (i.e. the if else statement given on the site) causes the time-out error.

I am using Python 2.7.16 and unrealcv v.3.10 in a Linux environment (Ubuntu). What could possibly be causing this time out error?
