But still, my python version is still 3.7.7
What is the problem and how to fix it?

This command usually will update to the latest version, but it seems this is not working for you.
conda update python
You can try this instead (Latest stable version is 3.8.3):
conda install python=3.8.3
However, you may want setup a new environment to be able to use multiple versions of python as upgrading may break your python scripts that run in 3.7.7. You can do this by using conda to create a new environment and then switch between the environments while you are testing and upgrading your scripts.
conda create --name test2 python=3.8.3
Also, the problem with the update command could be several. For example, if the channel list does not have a more recent version of python that is compatible with your environment, it won't update. To troubleshoot this we would need more information, such as
conda info
and
conda config --show
Think the problem is caused by mixing conda and pip installs in the same environment. This can be dangerous, as it will cause problems with some new installs or upgrades later on. conda won't know about pip details, and pip won't know about conda details. I suspect your Python upgrade has a dependency on one of the files installed through pip and gives up after a while.
Best practice is to use conda install if at all possible, and to create and use another environment. But if you still need a package that conda can't provide, then you can use pip. However, take note of the revision for that environment in case you have to roll back the pip install later.
To see the source of the install, look at the channel column. For example:
altgraph 0.17 py_0
amqp 2.5.2 pypi_0 pypi
imbalanced-learn 0.6.2 py_0 conda-forge
altgraph was installed using conda, amqp was installed using pip. The source for pip is the pypi website, that is why you see pypi in the last column (channel). Also, i can see you used the conda-forge channel for a few packages, such as imbalanced-learn. To change this environment in the future, you may need to add -c conda-forge

Why does geopandas throw an assertion error, when the conditions seems to be met?

I am trying to make a WFS request and create a GeoDataFrame (from the geopandas library) with this data. However, when I run my code, an assert raises an error:
assert len(bbox) == 4
I do not know what is causing this error, as when I print bb I get a string of four coordinates separated by a comma:
print(bb)
173600,443600,174600,444600
type(bb)
str
This is my code:
import geopandas as gpd
from requests import Request
# extract only buildings on and around WUR campus
url = 'https://geodata.nationaalgeoregister.nl/bag/wfs'
layer = 'bag:pand' # see wfs.contents
bb = ','.join(map(str, bbox)) # string of bbox needed for the request url
# Specify the parameters for fetching the data
params = dict(service='WFS', version="2.0.0", request='GetFeature',
typeName=layer, outputFormat='text/xml; subtype=gml/3.2',
srsname='urn:ogc:def:crs:EPSG::28992', bbox=bb)
# Parse the URL with parameters
q = Request('GET', url, params=params).prepare().url
# Read data from URL
BuildingsGDF = gpd.read_file(q)
The last line (BuildingsGDF = gdp.read_file(q)) throws the error from the assertion, i.e. when I try to read the result of a WFS request into a GeoDataFrame object (from the geopandas library).

You don't have a list with four elements, you have a string.
To solve this, split your string to create a list before the assert, like bb = bb.split(',').

as you see there is something suspicious here in pip list:
-atplotlib
I do not know what is that! it
looks like matplotlib without first letter m
I have search a lot and did a lot of efforts based on this
Getting an error that reads: ModuleNotFoundError: No module named 'matplotlib.artist'
https://github.com/matplotlib/matplotlib/issues/6771/
like, reinstall matplotlib, reinstall anaconda ...
but it does not work! In my view, it might be something related to the path, but I can not find the solution.
I also uninstall my anaconda two times still have the problem!
any suggestion would be appreciated

Go to this location
~\AppData\Roaming\Python\Python37\site-packages\
There will be two folders named as
~atplotlib
and
matplotlib
Please rename ~atplotlib to matplotlib
The system will ask you that there is another folder with the same name, so do you want to merge.
Select merge option.
In my case, this resolved the matter.

I also had similar problem, the below command solved the problem, run it in anaconda command prompt.
conda install matplotlib --force
source: https://github.com/matplotlib/matplotlib/issues/6771/

I had the same problem using Python 3.9. I had no folder named ~atplotlib so I couldn't merge it as suggested. I however found ~andas (pandas) in site-packages which I attempted to merge but was unsuccessful.
I uninstalled matplotlib using "pip uninstall matplotlib" and then reinstalled pandas after removing all pandas folders in site-packages. I noticed the numpy was included at the same time and created a new folder ~umpy so now I just removed everything again that contained numpy, pandas or matplotlib from site-packages (after uninstalling via pip).
Then I installed the modules in the order pandas, (numpy included), matplotlib using pip. And now finally it works. Utterly confusing.

I have done all steps including uninstalling,
How to remove anaconda from windows completely?
using anaconda clean,
completely removing all folder related to python in C:\Users\myusdername
removing from path
uninstall by anaconda
I just nopticed that the error says that
AppData\Roaming\Python\Python37\site-packages\matplotlib\pyplot.py
I manually remove python form the
AppData\Roaming\Python\Python37
r=then it works!!

I face the same problem and I used the below command. Please use this command in Anaconda prompt.
>conda install matplotlib

after upgrading Matplotlib check this as well
Go to this location
~\AppData\Roaming\Python\Python37\site-packages\
and check the folder name ..
for some weird reason matplotlib is saved as ~atplotlib folder.
just rename ~atplotlib folder as matplotlib

I had the same problem. Resolved by installing the 'matplotlib-base" in anaconda.
Follow the below steps for the same:
Open Anaconda navigator
Choose the "Environments"
Choose "base(root)" environment
select the option "All" then Search for "matplotlib"
choose matplotlib-base Then Click on botton
Restart your JuputerNotebook kernal and then import the matplotlib

Why am I getting an error when importing geopandas in my jupyter notebook?

I installed geopandas using the comand conda install --channel conda-forge geopandas
Then, I try to import geopandas in my jupyter notebook.
import geopandas as gp
And I get the following error:

I have tried fixing it using conda config --set channel_priority strict and my .condarc file looks like this:
channels: [conda-forge, defaults]
channel_priority: strict
Yet the problem persists. How do I fix this?

Conda export giving useless .yml file

I'm working with an environment named gcloud, with many google APIs packages installed. I wanted to export said environment to install it elsewhere, but when I do that I get a very useless .yml file. I run:
conda activate gcloud
conda env export > gcloudenv.yml
Which brings this:
name: gcloud
channels:
- defaults
prefix: C:\Users\usr\Anaconda3\envs\gcloud\envs\gcloud
So there's no libraries listed, even though I have installed many. What could be happening?
This is conda list's output:
# packages in environment at C:\Users\jeco_\Anaconda3\envs\gcloud:
