Error occurred by clicking 'conda' tab on Jupyter notebook

The solution mentioned above did not work for me. Can anyone help me?
When I opened "Jupyter notebook" from Anaconda, it successfully opened. Then I clicked 'conda' button,

appeared.

I also changed 'jupyter_config.json' file.
{
"JupyterApp": {
"kernel_spec_manager_class": "nb_conda_kernels.CondaKernelSpecManager"
},
"CondaKernelSpecManager": {
"kernelspec_path": "--user"
}

}
These are the versions I have.

OS: Windows 10 (64bit)

jupyter core : 4.7.1

jupyter-notebook : 6.2.0

qtconsole : 5.0.3

ipython : 7.21.0

ipykernel : 5.3.4

jupyter client : 6.1.7

jupyter lab : 3.0.14

nbconvert : 6.0.7

ipywidgets : 7.6.3

nbformat : 5.1.2

traitlets : 5.0.5

And I created 'jupyter_notebook_config.py' and added the sentence below.

#c.EnvironmentKernelSpecManager.conda_env_dirs=['C:\Users\Yusuke\AppData\Roaming\jupyter\kernels\python3']

I wrote

python -m ipykernel install --user

but it did not work for me.
This took me two weeks! Thank you!

Hmm.  I just noticed something that I didn't dawn on me at the time in https://github.com/jupyter/notebook/issues/4079 and that is that EnvironmentKernelSpecManager is from a different project - similar to nb_conda_kernels.  It clearly looks like you're using nb_conda_kernels but I wonder if there's a mixture of settings between these two "custom" kernel spec managers.
Also, you should probably stick with a single source for your configuration and try to eliminate this message:

as this may be leading to some confusion as well.

I'm curious what is produced if you run jupyter lab --debug.  (also, it would be good to add --debug in general when troubleshooting).
I'm hoping someone here knows what's going on with the nb_conda handlers in the traceback.  Looks like some executable is not available.
And, yes, it appears as though the mention of EnvironmentKernelSpecManager has been eliminated, so that's a good simplification to resolving this.

Thank you, kevin-bates!

Then, the message below appeared.

Is this what you metioned?

Are there other options listed in the dropdown list?  This is showing the kernel option associated with your base conda environment.  Is that the conda environment in which you want your kernel to run?
In the Jupyter Lab launcher, you should see a tile for all of your conda envs, plus tiles corresponding to other configured kernels:

@yuskeaita the feature you want to use is related to this package. If you want to manage your conda environments.  Starting from v5, you could still manage your conda environments but either from JupyterLab or from a standalone tool.

Indeed, this looks like an issue with nb_conda and not nb_conda_kernels. I agree with @fcollonval 's suggestion about gator, which is a great package.


Heroku Deploy Fails

The error message that stands out to me is Caused by: LoadError: cannot load such file -- mongoid-slug.
Once again, any help/insight would be greatly appreciated!

Adding the pg gem to my Gemfile fixed the issue. I really don't understand why but this issue does not appear related to mongoid-slug so I am going to mark it as closed 😄

You are unlikely to be using PostgreSQL and MongoDB in the same problem, so you do not want to add pg to your application. I suspect your production configuration is incorrect and tries to default to PostgreSQL.

@dblock Thanks for the response. This is what my production configuration looks like.

  end

end

I can not tell what is keeping a reference to PostgreSQL as I have followed several outlines on how to remove active record completely from the picture. But it appears there is still something holding on to it.

What's in your database.yml?

@dblock I do not have a database.yml file as I deleted it.

Good ;)
Look at "Getting Rid of Active Record" in https://mongoid.github.io/old/en/mongoid/docs/installation.html and make sure you've done that.

Thank you so much! Will report back if I am able to remove pg completely!

After following that guide to its entirety (at least I think), there is still something causing my heroku builds to fail without the pg gem. I removed
require "active_model/railtie"
require "active_job/railtie"

from my application.rb file which appeared to be the only thing I haven't already done in that guide.
If there is anything else you could think of that could be the culprit, it would be greatly appreciated.

end

If you put the project up on Github I can take a look when I have a moment, but no promises.

The only other thing I can think of is that I am using mongoid-rspec for my tests and I was receiving an error like this:
Failure/Error: raise ConnectionNotEstablished, "No connection pool with '#{spec_name}' found." unless pool

      ActiveRecord::ConnectionNotEstablished:
        No connection pool with 'primary' found.

So in order to get around this, I found a solution that caused me to create this file:
module ActiveRecord::TestFixtures
  def before_setup
    super
  end

  def after_teardown
    super
  end
end

Which ended up resolving the issue. This has to be it somehow in my opinion.

You're still importing ActiveRecord somewhere and this shouldn't be necessary.

I had active storage still hanging around. Problem solved. 😄 Thanks again for the help!


updateTranslations should not update language

First time you open our app, all views are instantiated with english because TranslationsManager.loadTranslations() updates currentLanguage with processLanguage(dictionary).
processLanguage(dictionary) gives back the latest entry in the translations (which in this case is english)?
However If the user has his phone in chinese, when TranslationsManager.updateTranslations() is run, it changes all the cells and later instantiated views to chinese - so we have a lot of mixed languages.
maybe just be consistent and use only the locale on the phone OR the languageOverride.

We'll take a look at this, thanks for reporting it

NaNs in JSON data

Sometimes NaNs still appear (I believe in the registration scalars). I can't find a reliable way to reproduce it, but it occasionally still happens under certain conditions.
How should I handle these?

Ahhh, can you send an example where this happens?

A scenario I found is if you get 2 objects very poorly aligned like in the picture.

Could you save them both and send to me?


BUG: unexpected results in arm64 and x86 for TEstNewPanic

when running test on arm 64bit i got and error:
https://github.com/willf/bitset/blob/1a37ad96e8c1a11b20900a232874843b5174221f/bitset_test.go#L981
i'm reading the Cap returns the total possible capacity, or number of bits , but reading the code of the test, i have not so clear if the xpected number are 0 or something!, in arm 64bits and i318 32bits got:
=== RUN   TestNewPanic
--- FAIL: TestNewPanic (0.55s)
	bitset_test.go:983: Unexpected value:<PHONE_NUMBER>

seems the test got a 0 value, but documentation does not explainme so much
i need this to clear package and run in embebed devices with linux
the sources said:
// Cap returns the total possible capacity, or number of bits
func Cap() uint {
	return ^uint(0)
}

the test expected zero? previous test in https://github.com/willf/bitset/blob/1a37ad96e8c1a11b20900a232874843b5174221f/bitset_test.go#L963 proves and works.. but later the https://github.com/willf/bitset/blob/1a37ad96e8c1a11b20900a232874843b5174221f/bitset_test.go#L980 faild! i cant understand and as we can see its not related to 32 bits, due happened in arm 64

I'm not sure it is a bug.
However, the test might be bogus. It seems to try to allocate a super large bitset and it expects it to fail. If it does not fail, then it fails the test.
At a minimum, the test should be documented.
For the record, I cannot verify the issue an aarch64 processor:
$ uname -a
Linux Softiron 4.4.36-8-default #1 SMP Fri Dec 9 16:18:38 UTC 2016 (3ec5648) aarch64 aarch64 aarch64 GNU/Linux
$ go version
go version go1.6.1 linux/arm64
$ go test
{0,1,2,3,4,5,6,7,8,9}
PASS
ok  	github.com/willf/bitset	0.102s

@willf  I can give you access to my aarch64 machine.

This test seems to fail on i686 and armv7hl for me (both these systems are 32-bit.)

I removed the nonsensical test. The reason it fails on 32-bit systems is that for the test to pass, there has to be a panic (out of memory). This is not a very good test. If one wants to test out-of-memory conditions, it should not be done in such a manner.


Switch from using a SQS Queue to SNS Web Hooks

This is blocked on merging https://github.com/pypa/warehouse/pull/3580.

We should ensure appropriate DeliveryPolicies are set to help increase reliability of SNS -> warehouse.

I've added a delivery policy to the SNS topic now, it is:

Immediately retry up to 5 times without a delay.
Retry up to 5 times with a 5 second delay between attempts.
Retry up to 65 times with a exponential backoff scaling from 5 to 30 seconds.
Retry up to 25 additional times with a 30 second delay between attempts.

I have no idea what the right policy is here, and maybe something simpler is better? but that should chew up all 100 retries before the hour is gone.


sbt completion json forget current search term

When searching for let's say run, the autocomplete list in activator looks like this:
{
    "type": "sbt",
    "subType": "PossibleAutoCompletions",
    "serialId": 3,
    "result": [
        {
            "append": "",
            "display": "",
            "isEmpty": true
        },
        {
            "append": "ner",
            "display": "runner",
            "isEmpty": false
        },
        {
            "append": " ",
            "display": " ",
            "isEmpty": false
        },
        {
            "append": "time:",
            "display": "runtime:",
            "isEmpty": false
        },
        {
            "append": "Main",
            "display": "runMain",
            "isEmpty": false
        },
        {
            "append": "::",
            "display": "::",
            "isEmpty": false
        }
    ],
    "partialCommand": "run"
}

It's missing the run command, but we have two empty commands ("" and " ").

I guess it depends on what display is supposed to show.
When I type run<TAB> I see:
root> run
::         runMain    runner     runtime:

Do you suggest we display the following?
root> run
run        run::      runMain    runner     runtime:

I don't know what to do with distinguishing run vs run  (with space). Maybe we can omit that from display for now by saying display "".


Creating VM using virtualBox throws IP error

OS X
Docker version 18.03.0-ce, build 0520e24
I am walking the tut (https://docs.docker.com/get-started/part4/#create-a-cluster), and am getting the following error:
$ docker-machine create --driver virtualbox myvm1

At this point I see the VM running in VirtualBox, and I am able to SSH to it, but it is not exposing a URL/IP:

Can someone point in the right right direction as to what I am doing wrong? It feels like a VirtualBox setting I am overlooking (I clean out my old VBox and install latest), but I am lost as to what settings it needs.
Thanks!
