Navigator hangs at loading applications

kfeaginsiii commented 5 years ago

Actual Behavior

Anaconda hangs at splash screen, 'loading applications' Clicking on the splash screen triggers a 'Python is not responding' windows message

Cmd window output: (base) C:\Users\KFeagins>anaconda-navigator <urlopen error [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond> <urlopen error [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond> <urlopen error [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond> <urlopen error [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond> <urlopen error [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond> <urlopen error [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond>

Expected Behavior

Anaconda Navigator should load.

Steps to Reproduce

Open Anaconda Navigator. Note, I am behind a proxy. I add this as the output suggest a connection issue.

Discussed with a co-worker. Apparently it will open, but takes a really long time (>10 minutes) if left alone. I was clicking the splash screen, which is where I was encountering the error. That said, it looks like the issue should be closed/renamed, as it is likely some of our security software stepping on it.

Thanks for the detail explanations!

I found an solution for freezing at "Loading applications". Try change the file at anaconda3\Lib\site-packages\anaconda_navigator\api\conda_api.py at line 1364 from data = yaml.load(f) to data = yaml.safeload(f)

bobbyroberts99 commented 5 years ago

I've been using Anaconda Navigator without issue for a while, but today it hung at 'loading applications.' This suggestion did the trick for me.

MichlF commented 5 years ago

That worked for me too.

ss3456 commented 5 years ago

Worked for me. Thank you :)

evan-blaisdell commented 5 years ago

Only one comment since December and then four within minutes. Crazy. And it worked for me too.

MartynWimpenny commented 5 years ago

After an hour of updates and installs this little nugget sorted it!! Think its a windows update thing - well done Bill!

TheJB2001 commented 5 years ago

Thx dude.

palakgupta1020 commented 5 years ago

MartynWimpenny commented 5 years ago

No probs – maybe a defender thing.

Worked for me too! Thank you so much for sharing =)

Had to restart my PC, but this solution worked. Thank you!

swdev1202 commented 5 years ago

You are awesome!

nico2g commented 5 years ago

I do not seem to have a site-package folder in my Anaconda version (Mac). Any ideas?

ss3456 commented 5 years ago

I couldn't find it either but then I searched for it in finder and it came up

jveitchv commented 5 years ago

Tried Anaconda for the first time with Windows 10 and exact same problem. Exact same solution.

eddiebeltran33 commented 5 years ago

This solution also works for Ubuntu 18.04. Thank you so much!

tharindu99 commented 5 years ago

awesome.. worked for me .. MAC one

harsh204016 commented 5 years ago

Thank you it worked for me also 👍

Jihad commented 5 years ago

wow.. it worked like a charm!

agnimish commented 5 years ago

That was awesome. It worked very well. Thanks!

ankon111 commented 5 years ago

This worked for me too. Great suggestion.

didier1969 commented 5 years ago

That worked for me too ! Many thanks !

pikami772 commented 5 years ago

Seems like you were right. I fixed the issue just by changing firewall zone on my Fedora 30, no changes to the file were necessary.

ghost commented 5 years ago

Slightly ironic that dev tool hangs on load. Wait though, and eventually it should dig itself out after looking unresponsive for around 10 min.

aint nobody got time for dat... keep the issue open

ismailsu commented 5 years ago

load > "safeload" works for me. Thank you...

Duvaragesh commented 5 years ago

"data = yaml.safeload(f)" worked for me too. Thank you :)

Svetko commented 5 years ago

Had the same issue, seemingly caused by limitations in corporate internet settings. Loading Anaconda Navigator took a lot of time, staying at "loading applications...". Furthermore, updating package index from the Environments page in the Anaconda Navigator would hang (without any timeout).

using the solution helped in my case as well! thanks!

CusiniM commented 5 years ago

"load > safeload" worked for me as well on rhel7.

MulesNose commented 5 years ago

Excellent !!

KermodeS commented 5 years ago

This doesn't work for me. On Windows 10, Ubuntu installed on WSL. After updating Anaconda this issue started (haven't updated in a while). 1) I uninstalled and reinstalled Anaconda, did the updates, but this did not fix it. Seems to have made thing worse lol, now I get a "conda: command not found" error before the command line appears. 2) Changed file as suggested saved then restarted computer. Confirmed file was still with the update but the problem persists.

What other ways can I try to solve this? Attached photo, I hope it helps! Loading applications problem

gabriellima commented 5 years ago

The change from data = yaml.load(f) to data = yaml.safeload(f) did the trick for me as well.

KermodeS commented 5 years ago

It's strange, I edited the code as shown below but the error keeps arriving showing yaml.load(f) not yaml.safeload(f). I only found one instance of the code. Is there something else I need to do, aside from adding "safe" to the line of code to make this edit active?

I noticed that this section of code seems to be in between these "" "". Could this be the problem?

Loading applications problem 2

dcardonav commented 5 years ago

The fix worked like a charm for me. Thx!

drumttocs8 commented 5 years ago

Solved my issue on win10. Seems like this should be the way it comes.

mjtpena commented 4 years ago

Awesome. changing it to safeload(f) did the trick.

wikwok commented 4 years ago

worked for me too! brilliant! thank you!

karma0san commented 4 years ago

This didn't work for me but running the navigator as admin solve the problem for me.

rickmunene commented 4 years ago

Great! Thanks, this worked for me after weeks of trying other solutions.

grgsolymosi commented 4 years ago

If somebody didn't find the code line above, for me under win10 the line was:

data = yaml.full_load(f)

in the line 1391 on the same path as mentioned above.

Changing it to:

data = yaml.safe_load(f)

solved my issue as well.

eljitall commented 4 years ago

Try first the followings lines, if it doesn't work then try the above code line. conda update conda conda update anaconda-navigator

faberfred commented 4 years ago

I have got the same problem, but no solution is working for me! I use ubuntu 18.04 and the latest anaconda. conda version : 4.8.3 conda-build version : 3.18.11 python version : 3.7.6.final.0

I changed yaml.load(f) to yaml.safe_load(f) within two files:

~/anaconda3/lib/python3.7/site-packages/navigator_updater/api/conda_api.py and ~/anaconda3/lib/python3.7/site-packages/anaconda_navigator/api/conda_api.py without any result.

Does anybody have any ideas? Thanks for your help

eljitall commented 4 years ago

@faberfred try to update the navigator by typing: ~$ conda update conda ~$ conda update anaconda-navigator

eljitall commented 4 years ago

conda update conda conda update anaconda-navigator

faberfred commented 4 years ago

@ eljitall: thanks for your quick reply. I did that already but it didn't work! It is really strange: it works perfectly if I am offline. But it always freezes if I start anaconda navigator if my computer is online.

ariesandes commented 4 years ago

Well. I am a mac user. Anaconda and other Coda commands hangs too until ... I found my security network monitor (Little Snitch, Hands Off!, etc) block conda and anaconda. Solution: I stop those monitor and Anaconda-Navigator and Coda works fine! Then I stop Anaconda, run those monitor again, run again Anaconda-Navigator and set up the permissions on my security network monitor (for python 2.7 or 3.7). From then all is ok. No more hangs.

mattterry13 commented 4 years ago

I've tried all suggestions on this thread and still having an issue. Like @faberfred it loads fine if I'm offline. Does anyone have any other suggestions? I'll have to stop using Anaconda if I have to disconnect from the internet every time I want to launch the navigator.

haoruilee commented 4 years ago

Try this in anaconda prompt: ··· chcp 65001 anaconda-navigator ··· This finishes my problem.
