Google Colab context-sensitive help does not work - google-colaboratory

I'm following this tutorial which shows how to get a list of functions or data available in a module. Tab, shift-tab, control-tab do not produce any such list.
Also, control-click on a function also results in "no definition found".
How do I explore the code of examples in google colab?

How to solve assertion error in Google Colab?

I'm attempting to write some code to generate a model for 3D segmentation. I'm using a model code provided by the creators of Stardist to write my code but I keep getting an assertion error and I'm not sure how to fix it.
Here is the code provided:
Screenshot of the code from Stardist github page
Here is my attempt at reconstructing the code with the error I get when I attempt to run it.
Screenshot of my code
I was wondering if people had any solutions for the problem I'm getting? I'm almost completely new to coding and using github as a whole so not sure if there's a way to create a direct download link, like they have, or if it should just be able to find my files directly off my hardrive. I also attach a picture of how my files are labelled so can't see why the code can't assertain they have the same labeling:
Image of my pathway for first, the images
and secondly, the masks.
Thank you all,

VS Code not showing model preview

I am currently working on a tutorial in Vue using VS Code. I am following along but I have noticed that the person who is teaching is able to see the data inside of the model.
For example, when he writes v-for="hero in her", it shows this:
When I do this, it just shows this:
Do you know which plugin is used to be able to read the data rather than what I am seeing? I notice that his shows a little spanner next to the names, whereas mine does not.
These are the plugins I currently use in VS Code that are related to Vue.

dgrid - how to download samples and find doc

This page shows a sample I want to reproduce:
http://dgrid.io/js/dgrid/test/Tree.html
(or any other of the samples here: http://dgrid.io/js/dgrid/test/)
I did a "view source" to see the code, but poking around and so far haven't found the data file "dgrid/test/data/hierarchicalCountryData".
It doesn't seem to be included in the code samples from GitHub (dgrid#1.2.1).
Also the normal doc/samples on the website don't show much about these tree features. I think I found it by doing a site:dgrid.io tree. So is this future research, or something currently available?

Tensorflow Documentation

I am increasingly irritated and frustrated by the Tensorflow documentation. I searched on google for documentation regarding
tf.reshape
I'm getting directed to a generic page like here. I want to see the details of tf.reshape and not the entirety of the documentation.
Am I doing something wrong here?
Do not Google about Tensorflow documentation, use the TensorFlow Python reference documentation and ctrl + f
The probably fastest way is to use the Tf documentation is:
http://devdocs.io/tensorflow~python/
Just type tf.reshape and you are done.
which can be also used offline and automatically updates the docs.
edit: even typing only res shows you the documentation.
Update for posterity:
With the new TensorFlow, the website is now indexed with Google, and it should also soon be indexed by other search engines.
I would suggest you use the GitHub repo as your documentation instead. https://github.com/tensorflow/tensorflow/tree/master/tensorflow/g3doc/api_docs/python/functions_and_classes
For example tf.reshape is in a single Markdown file https://github.com/tensorflow/tensorflow/blob/master/tensorflow/g3doc/api_docs/python/functions_and_classes/shard0/tf.reshape.md
To search for the document you want, you could use the GitHub search under that functions_and_classes folder.
An example is
tf.reshape() path:tensorflow/g3doc/api_docs/python/functions_and_classes language:Markdown
https://github.com/tensorflow/tensorflow/search?utf8=✓&q=tf.reshape%28%29+path%3Atensorflow%2Fg3doc%2Fapi_docs%2Fpython%2Ffunctions_and_classes+language%3AMarkdown&type=Code
which search for tf.reshape() under the documentation folder.
I use the non-official Dash/Zeal docset for TensorFlow:
https://github.com/ppwwyyxx/dash-docset-tensorflow
It is a very convenient way of browsing the TensorFlow documentation offline and it solves the problem you are describing.
Is this what you are looking for? Using the search functionality of the browser helped me find it.
I suppose that you have installed tensorflow in your computer and that you know the name of function that you may want to use.
So if you use some Python IDE, I think you can directly jump to the declaration or definition of this function and see the usage and explanation. That is the same documentation as online (although for some functions it is not very clear).
You can use the url for tensorflow documentation and add what you want to search..
The base url is:
https://www.tensorflow.org/api_docs/python/tf/
You can add what_ever_you_want_to_search after the /
Since Tensorflow r1.1 a search on google for items like 'tf.shape' now lists the appropriate page at the top of the search results.
This didn't work back in r0.10 and r0.11, maybe because there were many markdown formatting issues in the Tensorflow docs themselves.
Since you tf is developing best way is to go through the tf API. And it's good if you can follow these slides in http://web.stanford.edu/class/cs20si/

How to data parametrization in robot framework

I am basically trying to learn data parametrization in robot framework (mostly with web based testing as the context). I have 4 points which i am looking to get covered . All the four point are related to each other a lot.
First one - A code problem
I was looking to iterate a values of a list variable using for loop and was unable to access the nth value .
I am able to use the following with no errors:
Input Text //textarea[#id="MainContent_txtAddress"] #{Address}[1]
But when i am using a for loop to access the values I am getting this error:
Starting test: RobotFrameworkcode.Nsure.ForLoop
20150105 18:26:05.484 : FAIL : Resolving variable '${jobcode[i]}' failed: NameError: name 'i' is not defined
Ending test: RobotFrameworkcode.Nsure.ForLoop
The for loop snippet which is causing the error .
ForLoopTest
: FOR ${i} IN Range |0| |1|
\ Log to Console #{jobcode[i]}
Is there a better way to access the value of a list variable at n th element .
Are list variables similar to arrays ?
I want to pass values to textboxes in a data entry form in
parametrized format through excel sheet or csv or through a
collection of list variables representing a page, Is that possible
in robot framework ? Need help with examples and sample code on the
same . I could not find much content on the internet regarding the
same.
Any other ideas on how others did data parametrization in general in
robot framework. What robot framework tools or concepts where used
for the same ?
Thirdly,I would like to know if there are any good tutorials or
websites or videos to help learn robot framework in general . The
official documentation is good , but i am looking for more content
example wise,so as to enable the beginners to be able to relate
faster with the concepts.
1. NameError: name 'i' is not defined
When you use the extended variable syntax, everything inside the curly braces is evaluated by the python interpreter. However, the i in your code is a robot variable, not a python variable. Also, to access an individual element of an array you need to use $ rather than #. In order to do what you want, you need to do it like this:
Log to Console ${jobcode[${i}]}
2. Parameters from excel
You can create a robot library that reads data from a csv file. You can also do that with a .xls file. See this answer for an example of reading a csv file: https://stackoverflow.com/a/21859360/7432
3. Any other ideas on how others did data parametrization?
My team uses YAML files to define test data. It's also possible to read from XML files, or any other format that is readable via python. Robot lets you expose python methods as keywords, so anything you can do in python you can do in a robot test.
4. I would like to know if there are any good tutorials or websites or videos
Asking for pointers to tutorials and websites is off topic for stack overflow. However, are you familiar with the following resources?

https://github.com/robotframework/QuickStartGuide/blob/master/QuickStart.rst
https://blog.codecentric.de/en/2012/03/robot-framework-tutorial-overview/
Parameterization can be achieved using a csv or excel data source. Our team implemented it using excel, sharing the reference code that can help
