Getting an Internet error with Options_Add Ons

[I-Zapp]

Describe the bug When I click Options and then choose Add-Ons I obtain the Warning "There's an issue with your Internet connection ..." and then the list is empty.

Windows 10 with Internet fully working.

[ales-erjavec]

Can you click "Show Details..." and post its contents.

I may add that version 3.25 is working perfectly on my MacBook Pro, on the same network, with all addons

[ales-erjavec]

Can you open Options/Settings from the main window and check the Network tab to see if you have any proxy setting set, and if so that they are correct.

[I-Zapp]

[I-Zapp]

My MacBook Pro, on the same network, is pretty happy with the same settings (nothing, nothing)

[ajdapretnar]

Yes, I think you should enter your proxy details here, otherwise the connection won't work.

[I-Zapp]

Thank'you for your answer; as I said, my mac is on the same network and everything works with no proxi.

[I-Zapp]

Anyway, I have no proxy, should I try the router's IP?

Edit: tried the router's IP, same problem.

[ales-erjavec]

Can you open Orange, add a Python Script widget to a new workflow and run the following script

import os
from urllib.request import getproxies
print("getproxies():", getproxies())
print("env http-proxy:", os.environ.get("http-proxy"))
print("env https-proxy:", os.environ.get("https-proxy"))

[I-Zapp]

Here it is:

Python 3.7.6 (default, Jan 8 2020, 20:23:39) [MSC v.1916 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. (PythonConsole)

Running script: getproxies(): {} env http-proxy: None env https-proxy: None

[ales-erjavec]

Sorry the script was wrong. Can you repeat with

from urllib.request import getproxies, getproxies_environment
print("getproxies():", getproxies())
print("getproxies_environment()", getproxies_environment())

[I-Zapp]

Done, here is what I see:

Python 3.7.6 (default, Jan 8 2020, 20:23:39) [MSC v.1916 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. (PythonConsole)

Running script: getproxies(): {} getproxies_environment() {}

[ales-erjavec]

Well I'm stumped. Those are AFAIK the only sources of proxy config that could cause the proxy to be involved in the process.

[ajdapretnar]

I had a couple of similar reports recently from the users. I got the feeling that none were behind a proxy, yet they got this error. As if Orange somehow wrongly assumed there was a proxy involved. 🤷

[I-Zapp]

I can assure you I'm not behind a proxi: my macbook on the same network has no problem with Orange :-)

[markotoplak]

I double checked this and I do not know where to look for the bug either. @I-Zapp, if you think of anything that could help us debug it, please notify us.

[markotoplak]

@I-Zapp, can you please also try the following script in Python script widget?

import os
import requests
from urllib.request import getproxies
print("getproxies():", getproxies())
print("env http-proxy:", os.environ.get("http-proxy"))
print("env https-proxy:", os.environ.get("https-proxy"))
print("env for addons list:", requests.utils.get_environ_proxies('https://orange.biolab.si/addons/list'))

[markotoplak]

Also, are you perhaps using some kind of a VPN?

[I-Zapp]

Thank'you for your answer, and as I said a macbook pro on the same network works perfectly well with Orange. I am not using a VPN. Here are the results of your Python script:

Python 3.7.6 (default, Jan 8 2020, 20:23:39) [MSC v.1916 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. (PythonConsole)

Running script: getproxies(): {} env http-proxy: None env https-proxy: None env for addons list: {}

[I-Zapp]

Any other way I can download the addon to my filesystem and then trick Orange into thinking to get its addon from there? A config file maybe? On a different track: is there any cointainerized version that I can download from somewhere?

And, since we are here, I would like to have a contact with your maths guys (I am a mathematician and director of a phd and post-doc research group in ML and AI) to explore some possible opportunities for the future that I am sure you might find interesting.

Thanks

A.D.

[ajdapretnar]

@I-Zapp On Windows, you should have Orange Command Prompt (provided you installed Orange via its official installer). You can open the prompt and manually install add-ons, for example: conda install orange3-text

As for containerized version, see https://orange.biolab.si/blog/2020/2020-01-16-orange-cloud/. Also @acopar might be able to help with issues if needed.

For cooperation, please send an e-mail to info@biolab.si.

[I-Zapp]

Thank'you for your answer, I'll try and test the docker version next week.

Also, the command line version of the addon installer looks promising. Where can I find the names of the different addons? (orange3-text in your example).

AD

[I-Zapp]

Found it: https://anaconda.org/search?q=orange3

[I-Zapp]

I'm happy to report that thanks to the

conda install [addin name]

trick I have a working Orange3 on my main PC with al addons installed.

Now I'll have to study the container setup for my lab's cloud.

Thanks for now, I'll get back to you for the collaboration opportunities.

[markotoplak]

@I-Zapp, does the Datasets widget work for you? It also uses similar network libraries.

[I-Zapp]

Hi Marko, yes, the Datasets widget works perfectly.

Bye

I installed Win64OpenSSL_Light-1_1_1g.msi and get rid of this problem .My os is windows10.

[janezd]

@I-Zapp, can you try this?

I vaguely remember having some problems with conda or pip on some faculty computers, which were caused by incompatibility between Windows 10 libraries and Python's ssl modules.

[I-Zapp]

Tried it, same problem ....

AD

[dsoasti]

I installed Win64OpenSSL_Light-1_1_1g.msi and get rid of this problem .My os is windows10.

How did you install it?

[dsoasti]

I´ve installed this Win64OpenSSL_Light-1_1_1g.msi, but I still can´t make it work... Any help?

[markotoplak]

@dsoasti, your error message is different; for a solution to your problem see #4720.

[dsoasti]

Thanks!

[janezd]

I fear this will be filed under "unresolved misteries". Unless the error happens to somebody who can debug it.

[PerryGogas]

Thank'you for your answer, I'll try and test the docker version next week.

Also, the command line version of the addon installer looks promising. Where can I find the names of the different addons? (orange3-text in your example).

AD

How can I do this guys? like this? I did this and didn't work...

[ajdapretnar]

@PerryGogas These are just preferences, not installation dialogue. To install add-ons, go to Options - Add-ons. There, you don't need to type the commands, just select the add-on you wish to install. If you wish to add another package to Orange environment, go to Add more... on the right, and enter the name of the package as seen on PyPi.

Thanks! I tried it like that as you described but then I get this.

[ajdapretnar]

Are you using conda? Because this could be the underlying issue. Conda often doesn't have up-to-date Orange versions, so there might be incompatibility with certain add-ons (my guess). To further solve the issue I'd need the OS, Orange version and how you installed it.

I installed this as was required by Orange

The version is 3.36.0

I am trying to manually install the addons becasue I had this isssue:

The OS is Windows 10. I installed it from: https://oldorange.biolab.si/download/#windows

But when I click OK I get:

[ajdapretnar]

Thanks for your report. I think this warrants opening a new issue. I'll discuss with the team and open one if necessary.

Thank you so much! I use Orange in my graduate courses and my students now have this issue while they have to submit their MBA thesis...

It all started from installing the 3.37.0 version.

[ajdapretnar]

p.s. Could you also add the "Show details" from the second error after trying to install orange3-explain.

[PerryGogas]

Yes, I get this:

[ajdapretnar]

Idea from a colleague: did you remove the pip arguments you had entered in the Settings?

[ales-erjavec]

Can you try moving/deleting 'C:\Users\\%USERNAME%\AppData\Local\Orange\cache\networkcache' where %USERNAME% is your login name

[PerryGogas]

From: #6744 (comment)

Can you try moving/deleting 'C:\Users\%USERNAME%\AppData\Local\Orange\cache\networkcache' where %USERNAME% is your login name

I did it and while I was able to get to this screen:

After pressing OK to install the explain addon I got:

And the details say: ERROR: Invalid requirement: 'conda-forge::orange3-explain' WARNING: There was an error checking the latest version of pip.
