PyCharm ssh remote interpreter breaks every single restart
I use PyCharm version 2018.3.2 build #PY-183.4886.43 (just upgraded to 2018.3.3 #PY-183.5153.39, same issue)
I have a local git repository loaded as a PyCharm project. This repository is deployed to a remote machine. The remote (ssh) interpreter used by the PyCharm project uses this code. This setup worked fine for a long time, but recently I've been having problems every single day.
When I try running e.g. unittests from PyCharm (rightclick -> Run Unittests in file), I get the following errors:
Can't run remote python interpreter: Error connecting to remote host xxx
Couldn't upload helpers for remote interpreter: Auth cancel
However, when I change code, changes do get automatically pushed toward this same remote host with no problem. I can also browse to the virtual environment on the remote host (through PyCharm). Usually (almost all of the behavior I describe seems completely random and arbitrary) I can even open the python console and it will run the remote interpreter. Yet when I try running a file it refuses to work.
When I go to settings -> project interpreter, the selected interpreter and mappings are correct. However, under the package list it states "Nothing to show."
I have been unable to find out the steps to fixing this problem. I usually get it to work eventually through a process of repeatedly restarting, invalidating cache, creating a new ssh interpreter configuration that is -exactly- the same as the previous one (this fixes the "Nothing to show." but it still doesn't run files), etc. If I try this for long enough it tends to end up working but I can't find a pattern to it. It seems completely arbitrary and I fail to see why it can so clearly connect to the interpreter and the remote machine in some ways, but can't in others.
PyCharm is such a great tool to work with but sometimes it's infuriating due to its completely unexplainable and intransparent behavior.
Thanks for any help! Let me know if more information is needed.

With the help of PyCharm support I seem to have fixed it. If anyone else runs into this issue in the future: I fixed it by deleting the .pycharm_helpers directory in my remote home directory.
Thank you for your post.
I have the same issue. I can run the code remotely. but in the setting, it only shows "nothing to show" then it can't find any modules on the server from my local Pycharm.
I tried to delete /home/myaccountname/.pycharm_helpers directory and reboot or not reboot the Pycharm on my computer. But it still has "nothing to show"...
Yeah, the above thing seemed to fix it for me but the next day I had the same issue again. The behavior seems very random so I'm not sure if I really did fix it this time around, but I used to use an alias for the remote host. Now I'm using the ip address instead, and it's been working since. I have no idea how or whether it will stay fixed, but it's something PyCharm support suggested and so far so good... If you're using a name instead of an ip address as well it's worth a try.
I can confirm we had similar issues that was fixed by using IP address instead of the hostname, so please try it.
I have been using Pycharm for 18 months and I've suddenly started getting this. Is there a definitive answer on this. Its so annoying I've started looking at other IDEs
Hi David,
Can you please upload the logs (https://intellij-support.jetbrains.com/hc/en-us/articles/207241085-Locating-IDE-log-files) to our FTP (https://uploads.services.jetbrains.com/) and let me know the file name?
Hi, I used the IP address, but it didn't show the packages.
PyCharm can upload the files to my server and debug remotely, the only issue is this one.
Every time I create a new ssh interpreter. It is fine and shows the packages before I close the settings menu. But after connecting and uploading to the server, it becomes "Nothing to show".
The file I uploaded is shown above. I'm not sure if I use the correct part. Thank you!
@Xyang22
Please try reloading interpreter paths, let me know if it helps or if the issue is still reproduced:
@Andrey Resler
I didn't find such a refresh button...
It should be there, please refer to the screenshot:
@Andrey Resler I found the paths are not complete by default. And refresh didn't help.
And I tried to add some like yours. But it also didn't help.
And I downloaded some old versions. I found that 2018.2.1 was fine to find the packages. but I tried 2018.2.3 which couldn't find the remote packages.
That's very strange. Please also try deleting `~/.pycharm_helpers` directory from the remote host and recreate the interpreter, that's been known to help in many similar cases.
I had the same problem, but seems to work ok so far when I just authenticate by password in stead of ssh
@Andrey Resler I met the same issue with xyang22, my pycharm version is 2022, is it solved now.
