Jupyter Noterbook error - python

I just cannot use jupyter notebook. I have updated to the most recent version by ananota, and it still does not work.
The error message is listed below:
C:\Users\willian>jupyter notebook
Traceback (most recent call last):
File "C:\Anaconda3\Scripts\jupyter-notebook-script.py", line 3, in <module>

From your error it looks like the tornado package is not installed in your environment. Installing tornado with the command below should fix your problem.
pip install tornado

Requirement already satisfied: pycurl in /usr/lib/python3/dist-packages (7.43.0.1)
I also already imported the package with : Settings -> Python Interpreter
And finally i also used : "Inherit global site-package" option of the project and the problem is the same
I have no idea what else i can do
use command this command to install package -
pip3 install pycurl
and also check the Pycharm python version in for code compile

Anaconda navigator not launching windows 10 (Spyder as well)

I installed the anaconda 64 bit on windows 10. I can launch the prompt but when I try to open navigator thru the icon or thru prompt, I'm getting the error below. Can someone help me?

Also, Spyder is also not launching. I can launch Jupyter and prompt.

I did the solution explained here and it worked.
Error printed is related to ssl library and its natural for people to go and try reinstalling openssl library. But to fix this below steps have to be followed. Just now tried and confirmed this is working.
Copy the following files:
libcrypto-1_1-x64.* (.dll and .pdb files)
libssl-1_1-x64.* (.dll and .pdb files)
From D:\Anaconda3\Library\bin to D:\Anaconda3\DLLs.
Same issue is described in anacondas github page.
For me it works after installing "Win64 OpenSSL v1.1.1d Light"

Import error while trying to run jupyter notebook

An import error occurs when trying to run jupyter notebook
I'm trying to run jupyter notebook using anaconda (git bash platform), and as I type in jupyter notebook, an import error occurs every time. I tried to lauch it inside an environment, but the same error occured.

After reinstalling pyzmq (and I tried reinstalling conda too), the following error occurs:

I found a similar issue open on GitHub for zmq. The recommendation by GitHub user harsh23tyagi that seems to work for most is to run the following:
pip uninstall pyzmq
pip install pyzmq
Working with conda env, jupyter notebook worked in (base) env but gave the .libzmq error in (my_env).
To be able to run notebooks from my_env, this worked for me :
pip uninstall pyzmq
pip install pyzmq==20 (no version for pyzmq didn't fix the issue for me)
It seems that updating pyzmq to the latest version fixes this problem for me.
conda install pyzmq=22

Error installing Spyder in anaconda

Tried anaconda today , it seems fine but when I tried to launch Spyder each time I get this error: Traceback (most recent call last):

Any help regarding this ? Also how do I get python 3.6.3 in anaconda..?
The problem is you have two Python versions installed in your system: one in C:\ProgramData\Anaconda3\ and the other in C:\Users\Jaker\AppData\Roaming\Python\Python36.
Please uninstall one of them and the problem will be solved.

Python: pip is installed but not working in windows

I have installed python 3.6.0, you don't need to install pip manually if you are using python (>3.3). But When I am trying to access pip (pip --version), it throws me two errors which mainly relate to not finding the module.
Description is given below.
C:\Users\sharma6>pip --version
Traceback (most recent call last):
File "c:\python360\lib\site-packages\pip\_vendor\requests\packages\__init__.py", line 27, in <module>

from socket import error as SocketError, timeout as SocketTimeout

File "c:\python360\lib\site-packages\pip\_vendor\requests\packages\__init__.py", line 29, in <module>
import urllib3
ModuleNotFoundError: No module named 'urllib3'
Even when I import socket (>>>import socket)in python interpreter , It shows me "Can not found the module" error .
>>> import socket
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\python352\lib\socket.py", line 49, in <module>
import _socket
zipimport.ZipImportError: can't find module '_socket
Could someone tell me about the errors and how to resolve them because I need pip to work properly.
Add your all path in your system variable instead of adding in user variable.
It worked for me!!! :)
You should try to write
python -m pip --version
If this gives an error message, install pip by downloading get-pip.py from https://pip.pypa.io/en/stable/installing/ and install with
python get-pip.py
Installing with pip is then done by
python -m pip install [package name]
