Problem downloading and running a script that will install HNN about hnn HOT 12 OPEN

@andy-nord I don't see a reason why that should fail. Most likely you had a temporary network outage. If you try again, it should work

FYI, the HNN-GUI is not actively maintained at the moment. What you might want to do instead is install hnn-core:

https://jonescompneurolab.github.io/hnn-core/dev/index.html

and follow the tutorials along with the GUI tutorials. We can of course help you with the GUI installation if you insist going that route

Yes, it worked this time. Thank you! I downloaded Python and tried to get hnn-core in according to instructions https://jonescompneurolab.github.io/hnn-core/dev/index.html
but it didn't work.

from hnn.

Update. I just noticed that instead of Ubuntu I used Windows Command Prompt and it downloaded HNN together with NEURON and numpy and installed these. Now when I am trying to do the same in Ubuntu prompt it doesn't work again. Next step from tutorial Start HNN from https://jonescompneurolab.github.io/hnn/installer/windows/ doesn't work either. How to start with HNN from scratch?

from hnn.

Sorry, what do you mean that it didn't work? What did you try and what message did you see?

from hnn.

I downloaded Ubuntu 18.04 LTS and turned on WSL in Windows features. I also downloaded VcXsrv and went through all steps related to VcXsrv described here https://jonescompneurolab.github.io/hnn/installer/windows/wsl.html
Now when I am trying to run next step curl --remote-name https://raw.githubusercontent.com/jonescompneurolab/hnn/master/installer/ubuntu/hnn-ubuntu.sh
it shows only several 0s
when I am trying to run pip install hnn_core in Python I receive this error
ERROR: Command errored out with exit status 1:

from hnn.

NEURON does not have a pip distribution on Windows. I'm not sure if the WSL route can fix the problem, I have never used it. @ntolley any idea?

Alternatively you could download NEURON from here: https://www.neuron.yale.edu/neuron/download as we recommend on hnn-core documentation. On Ubuntu, you should not have any problem with pip install hnn_core. I think some of our developers are using it without any problems

from hnn.

@andy-nord just to confirm is the above error message in Windows command prompt or WSL (Ubuntu)?

Also appologies we are still behind on getting the native windows install in a stable state, the best route at the moment is WSL.

from hnn.

First error I received in Windows prompt when I used it by mistake instead of Ubuntu. I could download HNN by this way but could not execute second step and launch HNN. When I tried to use Ubuntu it didn't download HNN at all. When Ubuntu didn't work I followed advice from @jasmainak to install hnn-core from here https://jonescompneurolab.github.io/hnn-core/dev/index.html - Last error which I provided in the previous message was in Python.
Maybe you have any plans to create a video tutorial for beginners? This would help a lot in making things easier. HNN is fascinating tool but right now I am a little bit confused by multiple versions of HNN/ways to get it and numerous pre-requisites.

from hnn.

Really appreciate the feedback, a video is definitely a great idea. This week I will look to update the documentation for hnn-core to better clarify the installation.

I'll need to dig into the error message for HNN-GUI on windows, but in the mean time I think the best path is installing hnn-core on Ubuntu/WSL. If you run into issues on that route, I am happy to set up a meeting to troubleshoot.

from hnn.

Agree that looking into the Windows installation issue before our release is a great idea!

from hnn.

I would definitely appreciate any help/clarifications. I am afraid I will not be able to resolve this alone.
