I'm implementing widgets in my jupyter notebook (via anaconda). I tried first by using an old code from a professor of mine, but it's not displaying widgets.
I tried installing:
jupyter labextension install #jupyter-widgets/jupyterlab-manager
But it was unsuccessful
This was presented when I attempted installation of the package via windows command prompt:
C:\Users\davio>jupyter labextension install #jupyter-widgets/jupyterlab-manager

I expect to:
i) Be able to install all the required ipy packages in order to display widgets properly
ii) View and manipulate widgets properly
Thank you!!!!
Maybe if you had alredy python installed before installing anaconda, that's the problem. Try uninstalling python and only working with anaconda's python, that worked for me.
(Sorry for bad english)

I was having issues installing a package. I cancelled the install mid-solving environment.
Now, when I try to open Jupyter notebook, I receive the following error:
Traceback (most recent call last):

Jupyter notebook format depends on the jsonschema package:
https://pypi.python.org/pypi/jsonschema
Please install it first.
I tried installing jsonschema and importlib_metadata via conda install. When I do that, I receive this (for both):
# All requested packages already installed.
I tried turning it off and on again; I tried removing and reinstalling Jupyter. Neither worked. This is abhorrently frustrating. What the heck is going on, and why is Jupyter suddenly deciding to not work when it worked perfectly before the weekend? And more importantly, how do I fix this?
When I run a script in Anaconda Prompt, it works fine.
When I try to run it via PyCharm, I get this error related to the import of pandas.

Running the same script in Anaconda prompt...no problem
My run configuration in PyCharm uses the Anaconda python distribution?
It should be noted that I am not using envirnoments, just the base Anaconda installation. More worryingly I dont see ANY Conda options in the project settings in PyCharm which a lot of tutorials seem to allude to.
Seems like a problem with the path for your scripts. Are you sure You have included your scripts in the PATH variable? If so are you sure your libraries are downloading/installing in that path?
I went on to my computer today to work on a code I had been chiseling away at for school. I clicked on my anaconda navigator, only for anaconda to quickly show up in my running task bar at the bottom of my screen then disappear. I read on a other post that perhaps my Macbook wasn't updated and that was affecting it. I updated my Macbook and when I went to my launchpad to open Anaconda, it had completely disappeared. I tried opening a terminal and running "Anaconda-navigator" and I got this:
(base) xxxxx-MBP:~ xxxxx$ anaconda-navigator

I'm quite concerned, as my code was important for school and I can't access it. I tried installing it, but it said Anaconda was still downloaded, but it is nowhere to be found in my downloads or applications. Also, I ran the command to show my packages and they were still installed.
I just installed anaconda and I have udpated the PATH variable.
However, I cannot run any conda related commands.
Every time I run a command starting with "conda" I get the following error.
Can anyone help?
I am using macOs High Sierra 10.13.6.

I seem to recall something similar when I first ran Anaconda on my Mac as well. I believe I solved it by doing two things:
Uninstalling Anaconda (Link)
Reinstalling Anaconda (potentially in a different location, say, under your User home)
I think in the process of installation my PATH pointed finally to a different location than the Conda/Python install.
I'm using terminal on mac, and anytime I attempt to use pip, I get the following error message telling me that it cannot find a module named zlib:
$ pip --version

I've read several SO posts with the same error message, and have tried their solutions, including attempting to install zlib using homebrew, which fails, and updating my Xcode developer tools. I also installed pip earlier using python get-pip.py, and it said it installed successfully.
The reason I need pip is to install a package for use on python 2.7, but doing $ pip install "package-name" produces the same error as above. I have both Python 2 and 3 installed on my machine, if that helps. I'm kind of new to pip and using the command line in general, and I'm super confused; if anyone could help me out I'd really appreciate it.
This is the OP. I was able to fix the issue, and wanted to post my solution here in case it would help others.
Essentially I believe it occurred because Python2 is default on my machine, but pip is by default pointing to resources pertaining to Python3, or something like that. Doing pip2 --version instead provided the expected response.
