Vectorized version of gradient descent.
theta = theta * reg_param - alpha * (1 / num_examples) * (delta.T @ self.data).T
We should NOT regularize the parameter theta_zero.
theta[0] = theta[0] - alpha * (1 / num_examples) * (self.data[:, 0].T @ delta).T
the first code line ,theta include theta[0].
so I think can write like this:
theta[0] -= alpha * (1 / num_examples) * (self.data[:, 0].
The requirement to no longer specify source in the args dict tripped me (a layman) up when using a script that worked in 1.40 in 2.0.2. I couldn't work out what was wrong so I asked in a StackOverflow thread where @bryevdv ex

We've got quite a few standardized labels configured in our GitHub but no documentation on which labels to use and when.
We should add a "Labeling Issues" section to our CONTRIBUTING.md so this informational is accessible to people.

Hydrogen just gives me this error message when trying to run python code:
No kernel for grammar Python found
Check that the language for this file is set in Atom, that you have a Jupyter kernel installed for it, and that you have configured the language mapping in Hydrogen preferences.
To detect your current Python install you will need to run:

Hi all!,
Just want to share with the team some details I've been experiencing while I executed notebooks from command line using a yaml file.
First, let me show my case. I've bee parametrizing different notebooks to isolate data wranlging processes. To do it, I needed to use lists of dictionaries to specifiy keys describing my data, such as area or paths where some files were stored. As all
How to use Watcher / WatcherClient over tcp/ip network?
Watcher seems to ZMQ server, and WatcherClient is ZMQ Client, but there is no API/Interface to config server IP address.
Do I need to implement a class that inherits from WatcherClient?
According to https://readthedocs.org/projects/bqplot/builds/, the last build of "latest" was one year ago (Dec. 21, 2018).
Normally this happens each time something is pushed to master, maybe there's something wrong with the repo setup?
Feature motivation
Azure storage client is backward incompatible, there's an issue #757 for upgrading the azure connection to the latest client. The new version has an async interface that can be leveraged for the streams module, at least for downloads.
N.B. This is likely a 3~4h work and not a pressing need, so just putting this in the backlog.
Feature implementation
There's a
These classes were deprecated long ago and are now removed in Java 13. We should get ready and migrate these classes.
Some migration hints here:
https://docs.oracle.com/javase/9/docs/api/jdk/javadoc/doclet/package-summary.html#migration
Coming from a Python-in-Jupyter background, I notice that Tab works as you would expect (reveals all available methods/attributes), but Shift+Tab (signature hinting) does not. I could not find documentation on this. Is Shift+Tab not supported, or is my setup is incorrect?
Example:
type Foo struct {
name string
description string
}
func (f Foo) Qux(s string) string {
Would be really good to have some troubleshooting guide for using this tool to it's full extent!

from https://github.com/root-project/cling/blob/master/tools/Jupyter/README.md :

cd /cling-install-prefix/share/cling/Jupyter/kernel
maybe should be replaced with
export PATH=$PATH:/cling-install-prefix/bin
cd /cling-install-prefix/share/cling/Jupyter/kernel
because cling is required but not clang.

Note 1: This is not the same tab-completion bug for which many issues have already been opened (the one where a massive number of objects from the global namespace are displayed). This issue specifically has to do with unwanted abbreviation of filename paths. I haven't yet found any other reports of this issue.
Note 2: I also posted this to stackoverflow but am posting again here since I didn't
