Expected behaviour

Actual behaviour

Steps to reproduce:

1. XXX

Logs

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

XXX

Output from Console under the Developer Tools panel (toggle Developer Tools on under Help; turn on source maps to make any tracebacks be useful by running Enable source map support for extension debugging)

Can you paste the code that's causing the problem? Something in the imported code is invalid python.

[rchiodo]

Or even better if you could share the original notebook?

[jianboy]

Or even better if you could share the original notebook?

yes of course. the file is here:

http://cdn.yoqi.me/direct/2019-05-21/1_hello_tensorflow.ipynb

THe video of my operation:

http://cdn.yoqi.me/direct/2019-05-21/Video_2019-05-21_071457_edit.wmv

I can give you any information you need.

[rchiodo]

The import os change working directory stuff we put at the top of the file is messing up the

from __future__ import print_function

You can just delete the code that looks like this:

#%% Change working directory from the workspace root to the ipynb file location. Turn this addition off with the DataScience.changeDirOnImportExport setting
import os
try:
	os.chdir(os.path.join(os.getcwd(), '..\Import'))
	print(os.getcwd())
except:
	pass

That code is added to every import if you have this checked:

Otherwise I'm having trouble getting tensorflow to run. I keep getting this:

[rchiodo]

Yeah it looks like tensorflow doesn't have session anymore. I must have installed too new of a tensorflow

tensorflow/tensorflow#26816

[rchiodo]

Oh but you don't click on the tensorflow cell. So maybe my advice didn't matter. You're clicking on this cell in your gif:

And that is failing, possibly because you're using Python 2?

However in the video you posted, you mentioned the entire file wasn't there? Were you hoping it would open up the file as a jupyter notebook inside of VS Code?

Unfortunately the product doesn't work that way at the moment. Currently we expect you to work with '.py' files. The import notebook command merely extracts your python code.

We do have another open issue on inline notebooks though.

Something like this:

The function I want is just to preview the file when I open a jupyter file. and can run code.

[rchiodo]

I don't believe we have what you want (yet). Importing a notebook just turns it into the python code in your notebook. You then have to run each cell to view the output in the other pane.

[rchiodo]

If the hydrogen thing meets your needs, feel free to up vote the issue we have that I linked:
microsoft/vscode-python#4575

[rchiodo]

In the video you mention the 'right cannot display the html'. Can you elaborate on that comment? What HTML did you want? (Just wondering what we should do when we implement the hydrogen support)

thank you, I want preview the whole jupyter file. I hope that we can get this feature out quickly.

[jianboy]

when can I preview a jupyter file code ? I read Introduction of our plugin. it show have the function.

[rchiodo]

It does this now. All you have to do is click on the 'Run Below' command at the very top. That will run all 'cells' in the imported notebook. That's what the docs are showing anyway.

You probably want to uncheck this setting before you do the import though.

[jianboy]

the hydrogen thing meets mine needs! but it can only use in the IDE of atom.

I have set it up according to your suggestion.

[jianboy]

I often need to look at the contents of the jupyter file and then consider whether execute it.

[rchiodo]

Oh you want to see the current output. The last run you mean?

[rchiodo]

Our current implementation requires a rerun on every open. It's more like a terminal than a notebook viewer.

[jianboy]

Oh you want to see the current output. The last run you mean?

yes, you are right.

[rchiodo]

Hmm, that might be possible sooner (before we do the hydrogen thing). On import, just fill the interactive window with the current output.

[jianboy]

the plugin can privew the jupyter file. but can not run code.

[rchiodo]

Thanks. That's super helpful.

[jianboy]

I think if vscode can preview jupyter file ,and can run it. it may be better than the web page of jupyter notebook.
