Run python script in Linux with error - internet restriction, try out these options

[vegaviazhang]

Hi kensoh, Your RPA work is very attractive.Thanks a lot for this projects.

I encounter problem in run python script in Linux.I really hope you can help me solve the problem.
Following is my step to try：

1.install package in Linux

$ pip install rpa

2.write python script

*Here I hear from issues of this project for reference. I am using proxy to download https://github.com/tebelorg/Tump/releases/download/v1.0.0/TagUI_Linux.zip in python script.

import os
import rpa

os.environ['http_proxy'] = "http://192.168.200.18:xxx"
os.environ['https_proxy'] = "https://192.168.200.18:xxx"

r.init(visual_automation=False, turbo_mode=True)
r.url("https://www.baidu.com")
r.close()

3.Run the script

(vega_firenlp_super) zhangx@pve-gpu:~/a_project/p_supersimpletransformers_20211128$ python rpa_main_20220701.py
[RPA][INFO] - setting up TagUI for use in your Python environment

[RPA][ERROR] - failed downloading from https://raw.githubusercontent.com/tebelorg/Tump/master/TagUI-Python/tagui.sikuli/tagui.py...
[RPA][ERROR] - use init() before using url()

3.1 My attempt

• First, download success of the https://github.com/tebelorg/Tump/releases/download/v1.0.0/TagUI_Linux.zip .
• Then, I think it may be accidental factors, such as proxy reasons, that led to the error here.So I try again.

4.I delete the unziped file.

rm -rf /home/zhangx/.tagui

5.Rerun the script in step 2.

7.Try third.Repeat step 4,step 5.

I have no way to deal with it.0.0

• I don't install chrome in Linux. Because the linux is the server.It has no visual interface.

Hi @vegaviazhang thanks for sharing these detail information. I think the root cause is network policy (maybe from company, or from China), that is blocking automated downloading of required files from GitHub. One way is to run on a computer with no internet restriction and use pack() to generate the zip file to copy to your PC. Another way is to manually download the required files and set them up. See this link for detailed step by step instructions - #376 (comment)

Surprised! Kensoh .I have a try refer this link Today.#376 (comment).[download the required files and set them up.].

My confusion

• Run RPA TagUI with the Linux no need to install PHP.
• Is my understanding wrong?
• Thanks very much.

[kensoh]

Ubuntu Linux does not have PHP installed, you can install it and try again. See this Ubuntu Colab notebook for example to install PHP - https://colab.research.google.com/drive/13bQO6G_hzE1teX35a3NZ4T5K-ICFFdB5?usp=sharing

[vegaviazhang]

Year.I'll try it today and fill in the results later. ^.^

[vegaviazhang]

Hi.Kensoh.According to the above tips, I feel that success is only one step away
The steps I used to build the RPA Ubuntu environment using containers are as follows:
didn't get response for a long time

1 pull ubuntu images/install python/create container

$ docker run -d  --name vega_rpa ubuntu_python:20.04_3.8.3_sh  tail -f /dev/null

$ # enter container 
$ docker exec -it vega_rpa /bin/bash

2.install php/chromium-browser/rpa

$ apt-get update
$ apt install php -y
$ apt install chromium-browser -y
$ pip3 install rpa  -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn

All the above codes were executed successfully

• I set debug=True in r.init().Don't response also.
• Hope to get your reply.

[kensoh]

Hi @vegaviazhang thanks for sharing these details, they are very helpful!

Normally when init() is stuck, the most common reason is that it cannot connect to the Chromium process. This may be due to port 9222 not opened or restricted for the tool to make a websocket connection to Chromium process, or could be other reasons with initialising Chromium. Can you try to run following command from your terminal and see what happens?

chromium-browser --user-data-dir="~/.tagui/src/chrome/tagui_user_profile" --remote-debugging-port=9222 about:blank --window-size=1366,768 --no-sandbox

After that, run the following command in the terminal to see if Chromium process websocket connection is opened up

curl -s localhost:9222/json

If it is opened successfully, there will be some result with about:blank as the url and there is a webSocketDebuggerUrl string in that result. After you try the above, let me know your findings so that we can find a solution together.

[kensoh]

Also, I notice you did not initialise the virtual display. Before you do r.init(), you have to do the following (from the Colab example). It is initialise the virtual display for Chromium browser to be able to run without a real display.

import pyvirtualdisplay; display = pyvirtualdisplay.Display(); display.start()

[vegaviazhang]

Hi, kensoh. Today I have a try. Reslut are as follows.

1.repeated the problem that init() did not respond

• i wait for 20 minutes.

3.curl with no result

root@426a5eaa37f2:/# curl -s localhost:9222/json

End

• I look forward to your reply

[kensoh]

Thanks for the details! Can you try below from the terminal to see what happens? Below will run using headless mode browser, see if that can load and curl -s localhost:9222/json can return some results.

chromium-browser --user-data-dir="~/.tagui/src/chrome/tagui_user_profile" --remote-debugging-port=9222 about:blank --window-size=1366,768 --no-sandbox --headless --disable-gpu

[vegaviazhang]

Yes, I run the command using headless mode browser, it can return some result.

chromium-browser

From above so far, it looks like headless mode can return a websocket connection, however it is not working for virtual display. Maybe there is some unknown reason why the virtual display method is not working. You can try the following -

1. search the file ~/.tagui/src/tagui and change --no-sandbox to $headless_switch --no-sandbox. after that run import rpa as r; r.init(headless_mode = True) to see what happens
2. download and try the TagUI RPA engine (https://tagui.readthedocs.io/en/latest/setup.html) and run tagui /your_tagui_path/tagui/flows/samples/1_google.tag headless to see what happens

Above will try to isolate the issue to see if headless mode works for you and if the root cause is in the upstream TagUI RPA engine. So far, I haven't come across any user raising this issue, other than the recent similar issue at #404
