It turns out that my Anaconda-Navigator isn't working right so as my Anaconda installation is slightly out of date (4.2.0) I figured I'd start troubleshooting by updating. However, any conda Terminal command (I'm on Mac (Monterey)) gives a massive error, such as:
$ conda list conda

The only way I could even assess my Anaconda version (as $ conda -V throws something similar) was via
$ python -V
Python 2.7.12 :: Anaconda 4.2.0 (x86_64)
Weirdly, I also get
$ python3 -V
Python 3.7.3
[no Anaconda reference] despite the fact that Anaconda is definitely doing something for Python 2, and Anaconda 4.2.0 comes with Python 3.
Any help with sorting through this would be wonderful.

I am totally new to Python/Jupyter notebook.
Using Windows 11. I installed latest version python Python 3.11.1. Also latest Anaconda - conda 22.9.0.
My jupyter notebook (installed by anaconda) does not start from command line:
jupyter notebook

Conda documentation states "Anaconda supports Python 3.7, 3.8, 3.9 and 3.10. The current default is Python 3.9."
Should I just downgrade my python to 3.9 or 3.10 (I dont care) ?? Any other work arounds?
Updates
Could open the jupyter notebook from the conda prompt. Not stated using it yet. So lets see. If python compatibility issues need to be resolved - need to figure it out.
But, cant start the anaconda-navigator. When I try start from windows start menu - does nothing. From Conda prompt: I get the flwg error on the prompt: >anaconda-navigator Traceback (most recent call last): File "C:\apps\anaconda\Scripts\anaconda-navigator-script.py", line 6, in <module> from anaconda_navigator.app.main import main File "C:\apps\anaconda\lib\site-packages\anaconda_navigator\app\main.py", line 19, in <module> from anaconda_navigator.app.start import start_app File "C:\apps\anaconda\lib\site-packages\anaconda_navigator\app\start.py", line 15, in <module> from qtpy.QtCore import QCoreApplication, QEvent, QObject, Qt # pylint: disable=no-name-in-module File "C:\apps\anaconda\lib\site-packages\qtpy\QtCore.py", line 15, in <module> from PyQt5.QtCore import * ImportError: DLL load failed while importing QtCore: The specified procedure could not be found.
I encounter an error when creating virtual environment on Ubuntu-16.04.
In particular, virtualenv -p python myenv returns

SyntaxError: invalid syntax
meaning incorrect syntax in Python 3.5. However, I have set my default python version on Ubuntu to be Python 3.8.9 i.e., python -V returns Python 3.8.9.
So why does virtualenv refer to Python 3.5 even though Python 3.8.9 is default?
Additional info:
My virtualenv version is 15.0.1
The first line in the traceback refers to /usr/local/bin/virtualenv, which looks like this

sys.exit(run_with_catch())
Update:
Running python3 -m pip install virtualenv
returns

You can use the below command for ensuring that virtualenv refers to python3.8 by default
python3.8 -m virtualenv myenv
I'm aware of the -p flag, but whenever I use it to specify an interpreter, the resulting environment can't use pip. I want to use a python 3.x project and a python 2.7 project in the same application - as far as I know, the best way to do that is to install both interpreters with pyenv and make a virtual environment using virtualenv in each project folder, specifying the path to the correct interpreter. Here's what I did:
pyenv install 2.7.18
mkdir my_env
virtualenv -p ~/.pyenv/versions/2.7.18/bin/python my_env
source my_env/bin/activate
pip --version
and here's the output of pip --version (or anything involving pip):

Similarly, if I do the above with a version of python 3.x installed by pyenv,

It seems like this output could also be relevant, since a module is missing:
$ python -c "import sys
> for i in sys.path:
> print(i)"
~/my_env
~/.pyenv/versions/2.7.18/lib/python27.zip
~/.pyenv/versions/2.7.18/lib/python2.7
~/.pyenv/versions/2.7.18/lib/python2.7/plat-linux2
~/.pyenv/versions/2.7.18/lib/python2.7/lib-tk
~/.pyenv/versions/2.7.18/lib/python2.7/lib-old
~/.pyenv/versions/2.7.18/lib/python2.7/lib-dynload
~/my_env/lib/python2.7/site-packages
Pip works just fine, of course, when I use virtualenv as normal, e.g.
$ which python
/usr/bin/python
$ mkdir sys_env
$ virtualenv sys_env
$ source sys_env/bin/activate
$ pip --version
pip 20.0.2 from ~/sys_env/lib/python3.8/site-packages/pip (python 3.8)
and with that working, the path is
$ python -c "import sys
> for i in sys.path:
> print(i)"
~/sys_env
/usr/lib/python38.zip
/usr/lib/python3.8
/usr/lib/python3.8/lib-dynload
~/sys_env/lib/python3.8/site-packages
I don't quite know what I'm doing enough to find which part of the path the system python uses is missing for the pyenv-installed python or to figure out why it's missing.
I am trying to use a Python program written for Python 2.7. I am using a Macbook Pro running Catalina. The program is here: https://github.com/geoss/censumander. The program has two Jupyter Notebooks to practice with. I have Anaconda 4.9.2 installed and pip 20.2.4. When I open Jupyter Notebook it defaults to Python 3 and has no kernel option to change to Python 2. I have used the guide here to try to install the Python 2 kernel: https://ipython.readthedocs.io/en/latest/install/kernel_install.html.
When I run
python2 -m pip install ipykernel
I get back
Could not find a version that satisfies the requirement ipykernel (from versions: )
No matching distribution found for ipykernel.
I am pretty new to using Python (typically use R) and am trying to get the hang of stuff like this, so apologies if the answer here is obvious. I've tried the solutions here to no avail: Jupyter notebook with Python 2 and Python3 Kernel
I have also tried the solutions here: Jupyter Notebook - install python 2. The first solution
$ python2 /path/to/jupyter-notebook
is unclear to me as I don't understand to what file path the code points (for jupyter_notebook). (This is likely a consequence of my noobiness.)
The second,
conda create -n ipykernel_py2 python=2 ipykernel
conda activate ipykernel_py2
python -m ipykernel install --user
triggers the following traceback after the third line:

Thanks, all.
From version 5.0 ipykernel only runs on Python 3.4+ (from version 5.2 — 3.5+). To install ipykernel` for Python 2.7 you need an older version:
python2 -m pip install 'ipykernel<5.0'
For backports.functools-lru-cache install or force-reinstall it:
pip install -U backports.functools-lru-cache
or
pip install --ignore-installed backports.functools-lru-cache
Im new to programming, so I have met this trouble.

Can u help me to solve this issue, please? Thank u very much.
Im using:
- Ubuntu 16.04. (64bit)
- Python 2.7.12
- Python 3.6.0 :: Anaconda 4.3.1 (64-bit)
P.S: Ive tried to fix with dotenv, ensurepip(this got me answer that I dont have this package).
Not a full answer because I cannot tell you why this is happening, but hopefully this will help you find a solution.
I had been running into this problem with an venv. When I started from scratch trying to build rjsmin, everything went all right, that is when I noticed that the reason was that the venv that was failing was using Python 3.6, whereas the new venv was using Python 3.7.
According to your console output the anaconda you have is using 3.6, I think you might have break your install by manually upgrading packages using pip. You could try getting the newer version of anaconda, or go with a new, fresh install.
