I encountered a problem about socket connection failure.

[JasonChenhx]

I don't know why I encountered this kind of problem. I checked the code and found that there is no code related to socket. Is it because the communication between multiple GPUs requires socket?

[qinnzou]

We do not use the socket in our codes. Is it the problem when you are using cloud computing resources?

I think i meet the same problem when i run test.py, and the error message is like :

SOLVED. The problem is caused by visdom which is used for visualization. You need to type "python -m visdom.server" in Terminal and visit http://localhost:8097/ before you run test.py or train.py

I have tried a piece of code from Zhihu to solve this problem https://zhuanlan.zhihu.com/p/54389036?tdsourcetag=s_pctim_aiomsg The full code block is :

! npm install -g localtunnel get_ipython().system_raw('python3 -m pip install visdom') get_ipython().system_raw('python3 -m visdom.server -port 8097 >> visdomlog.txt 2>&1 &')
get_ipython().system_raw('lt --port 8097 >> url.txt 2>&1 &')
import time time.sleep(5) ! cat url.txt import visdom time.sleep(5) vis = visdom.Visdom(port='8097')
print(vis) time.sleep(3) vis.text('testing') ! cat visdomlog.txt

I try this code in colab and insert it before test.py. It solve the problem of socket connection error.

SOLVED. The problem is caused by visdom which is used for visualization. You need to type "python -m visdom.server" in Terminal and visit http://localhost:8097/ before you run test.py or train.py

Hi, I did this. First, I called python -m visdom.server, then I clicked the http://localhost:8097/.

Then I kept this open and then opened another anaconda command prompt. It was running but gave one error message "ERROR:tornado.general:Could not open static file 'C:\Users\tamim\anaconda3\envs\DeepCrack_Master\lib\site-package". But it was running.

so, by keeping this on, I called train.py in the another anaconda command prompt. Then the message was that "Without the incoming socket you cannot receive events from the server or register event handlers to your Visdom client."

Can you please explain where I made the mistakes?

I've no idea. Sorry it was a long time ago when i answered. Basically you need to run and visit visdom server before u train or test the model.
