Can't run jupyter notebook with pip

Just trying to run jupyter notebook with pip. What the hell is happening? I tried to run it like this "python -m notebook", because just "jupyter notebook" or just "notebook" doesn't even get recognized.

Your local installation of jupyter via pip is conflicting with your Anaconda installation. There are some situations where you may need more than one instance of python (e.g. if you need to test code with different versions of python, or some applications require a separate instance, but you seem like you might want to limit your installations to just a single instance.
Remember to use environments to keep your package list clean.

Python pytest hangs. For instance, "pytest --version" simply hangs

The following hangs:
PS C:\Users\Fowler> pytest --version
Notes:
I am in Windows 10.
By hang, I mean at least 5 minutes of waiting for the pytest --version to return...
While waiting for pytest, python.exe is using 100% of a logical processor on my computer.
I uninstalled all python installations with windows installer and I reinistalled python 3.8.0 in an attempt to fix.
pytest only fails when I am not using a venv. So, pytest does work using a venv.
However, I can't use a venv with vscode, because debugging with venv gives a strange "Session-1 timed out waiting for debuggee to spawn" <-- you would think the word debuggee would be a nice clue, but not much found with that word on google. I am guessing this is a different problem, but maybe related?
In summary, I can't debug python with a venv, and I can't run pytest unit tests without a venv. Probably, these items are unrelated... But, because of this catch-22, I will be sooo grateful for any hints to fix either problem.
When I hit <ctrl-c> to break out of the pytest "hang", the following is displayed (but changes a little bit at the end each time?:

And finally! Whew, in case this sheds any light, here is a picture showing the python process having fun eating up my CPU during pytest.py...
I would be oh, so grateful for any assistance or thoughts!

Fixed.
The answer appears to be
Uninstall python via the windows apps and features
Remove the c:\program files\python38 directory
Remove the ..\AppData\Roaming\Python directory
Reinstall
Not sure what the "root" problem was, but a total wipe of python fixed it. Note that the python windows installer does not remove enough python stuff.
Thank you #nneonneo for getting me thinking in the right direction.

You can just run pytest from priviledged (admin) cmd for the first time. For me the issue was fixed and pytest runs from ordinary cmd now without hanging.

I have the similar problem
after i install pytest-cov or allure-pytest, pytest will hang
if i uninstall them , everything is back to normal
I have tried to install different pytest version, It didn't help
but, I tried the method you provide(uninstall python, remove the diretories), it works~, great！
but, when I install allure-pytest again, it fails again.
finally, I found that, I can't install package in privilege cmd window
If I install them in privilege cmd windows, it will make pytest hang!
so, if anyone encounter the problem I have, you can try my way.

In my case, the package anyio, a dependency of JupyterLab, was causing this problem. It was installed at the administrator level. I uninstalled it and reinstalled at the user level and pytest started working again.

Using Ubuntu 18.04/20.04 + Python 3.8.2
My tests were hanging in a similar matter after showing results.
Removing pytest-cov didn't help.
What helped was moving from Python 3.8.2 to a newer version (like 3.8.12)

I ran into the same issue. In my case my IDE didn't load the correct conda environment. So make sure you're in the right environment for your application and use conda activate myEnv to change it if necessary.

Conda working but could not create virtual environment

I'm having problems setting up a virtual environment with Conda. Conda is working (I guess) when I tried commands such as conda --version.
But when I tried conda create -n mynewenv python=2.7 I got an error below.

UPDATE
Apparently conda is not working. I get the same error message with any other conda arguments such as info and list. The only working arguments are -h and -V to check help message and version check. How can I reconfigure conda? This is on a shared server.

Arcgis Pro 2.0 Jupyter Notebook Install Fails

I did a fresh windows install of ArcGIS Pro 2.0 to a local user location. I then used the python package installer to install spyder and jupyter.
I launched jupyter notebook from the python command prompt that resides in the start menu for ArcGIS Pro.
Jupyter launches, but creating a new notebook always starts with a dead kernel. ipykernel is installed according to the ArcGIS pro python package manager. The kernel error message follows.

FileNotFoundError: [WinError 2] The system cannot find the file specified
I've worked on this problem for a few days but I can't figure it out. I've looked at a number of posts that discuss connecting Jupyter and arcgis. They all make it appear possible if not easy, but this seems like a non-starter. What is missing, and why is the kernel starting dead? How do I fix it?

you said it's dead kernel though python is installed , assuming everything ok (versions, etc) ,that's means jupyter didn't recognize the kernel yet
The error is matching that of: issue
I think it's mostly the same , sometimes the kernels json files for jupyter need to be created in some folder (in windows it were in C:/Programs Data/Jupyter/.. ) before the first usage
launch the command (as admin):
python -m Jupyter kernelspec install-self
Then retry,

To fix it, run the python command prompt with the following:
(gee) C:\Users\thapa\AppData\Local\ESRI\conda\envs\gee>
conda activate tensorflow1
conda install ipykernel
ipython kernel install --name tensorflow1 --user
Restart ArcGIS pro, now it will work.

Error "%1 is not a valid Win32 application" when starting IPython Notebook (Anaconda 3)

How it all started...
I've installed Python 3 first (on Windows 8.1) to learn Python. Later, I took a Python bootcamp where they told me to install Anaconda, so I did. I later learned that this was Python 2, so I downloaded and installed Anaconda 3 which has Python 3.
By now things are redundant and confusing to know the packages that are installed. So I decided today to uninstall all Pythons (i.e. standalone Python 3, Anaconda, and Anaconda 3). I googled for instructions, and it seemed that all I needed to do was uninstall via the 'Programs and Features' in the control panel.
Now, I re-installed Anaconda 3, and I was able to run a .py file from cmd and in PyCharm.
Problem:
When I try starting IPython Notebook (I understand this is part of the Anaconda distribution), it gives me the following error message,
PS C:\Users\myPC> ipython notebook

I searched for this error message and was able to find some posting by others getting similar errors, but for different situations unrelated to starting IPython Notebook. I tried some of the suggested solutions in these, but none seem to help me getting IPython Notebook started.
At this point, I'm afraid that I may just completely mess this up even further...
How can I can fix this problem?

I got IPython Notebook back. I'm not really sure what's happening behind the scene, but this is what I did.
Uninstalled Anaconda 3
Re-installed Anaconda 3 (just to see if
something had gone wrong in the previous re-installation.
Needless to say, I still couldn't start IPython Notebook)
Installed Anaconda 3 (this time, 32-bit; previously I had been
dealing with the 64-bit Anaconda 3)
I was able to start IPython Notebook from cmd
For some reason, I have a bad feeling that I may still have left the problem somewhere unresolved; and may come back to bite in the future. If anyone has any suggestions on what to look into (e.g. cleanup), I would really appreciate it!
