I have seen this error posted in a few places but none of the sites give any viable solution.

The applications work if launched directly though (so for now, I'm going with that)

In case you need a detailed log, I have run the same command with --verbose and --debug options available here: https://drive.google.com/file/d/1Xump5Ns0FFX7N9Ujl0kqPZVNhXZgm4j1/view?usp=sharing

I found a solution for freezing at "Loading applications".
Try to change the file at anaconda3\Lib\site-packages\anaconda_navigator\api\conda_api.py
in function load_rc from

data = yaml.full_load(f) # around line 1391

to

data = yaml.safeload(f)  # quoting from Salim Tekin

Try the solution given by limkin092 in the link below:

https://github.com/ContinuumIO/anaconda-issues/issues/10461

It worked for me just fine.

  • I did read about it in another thread but in that case the error continued to appear and hence I hadn't considered it. I'll give it a shot in any case – Shravya Boggarapu Jun 02 '19 at 11:08
  • You should try reinstalling anaconda first and then try that procedure. To safely remove your current installation, refer to Surya in: https://stackoverflow.com/questions/22585235 – Bikramjeet Singh Jun 02 '19 at 13:01

    The line number is now 1391 and the original code is now `data = yaml.full_load(f)`. – Matti Wens May 28 '20 at 06:05

  • wow, I don't remember the situation where I got this issue now. I have changed job and can't even reproduce it now since I don't use anaconda anymore – Shravya Boggarapu Nov 11 '20 at 23:44

Try opening the navigator as administrator.

For me on windows 10, It worked with below steps

  1. tasklist | findstr "pythonw" ( shows Process IDs)
  2. taskkill /pid 99999 /f ( 99999 - is the PID of the process,kill all such process )
  3. changed the below line C:\anaconda\Lib\site-packages\anaconda_navigator\api\conda_api.py at line 1364 data = yaml.load(f) ( old one data = yaml.safeload(f) ( new line)
  4. start anaconda navigator from start menu

I had to uninstall a standalone version of python first. Once I did, then the install worked and the navigator launched fine.
