I was running python 2.7 in Anaconda2 in spyder 4 up until today with no problems. But now I keep getting the same error, when I make an environment and install python 2.7 and spyder in it:

This started happening after I reinstalled the package "pydicom" in the environment, and now nothing works. I have reinstalled anaconda2, used spyder --reset, and all other common suggestions.
Spyder 3.3.6 works in the base environment, but every time I make a new environment and install spyder in this, I get the same error. Any suggestions?
(Spyder maintainer here) To fix this problem, you need to install QtAwesome 0.7.3 in your environment. For that, please use the following command:
conda install qtawesome=0.7.3

Recently I have had a problem on debugging in spyder 5.1.1. I have checked online and note that they have some issue on debugging in spyder version 5. I have also tried to install spyder 5.2.2 but still not able to debug so I decided the downgrade to Spyder 4. However, it not working either , so I tired to uninstall Spyder and reinstall spyder 2.4.2 in anaconda. After installed , I cannot open spyder and I got the following message from a pop up window when I tried to launch spyder in Anaconda:
Application spyder launch may have produced errors:

I have the same questions on github but still have further problem on that after getting the advice from other experts. (https://github.com/spyder-ide/spyder/issues/17920#issue-1239365635) What should I do so that I could open the Spyder again?
I recently created a new environment with Anaconda Navigator and installed in it the Spyder IDE version 4.1.1. The problem is, whenever I try to launch it (via Anaconda Navigator), it raises me the following exception, and doesn´t launch at all:

But when I go to the root environment and try to launch from there Spyder version 4.0.1, it launchs with no issues.
I have just tried to upgrade everything in my main environment to the latest version (using conda update --all). Everything went completely fine until I actually tried to run python. I got this error message:

As you can see, it looks like a problem with sys.flags. I tried googling this, but I couldn't find anyone with the same issue. I am using python 3.6.7 (python didn't update itself). This error message also appears if I try to run python in the command prompt. Here is the output of running conda update --all. Hope you can help!
EDIT: I found an issue on this issue on github here, but this doesn't give any explanations on how to fix this.
NOTE: I have also tried to install a new version of python using the installer, but that didn't work either.
I somehow did it - I re-installed Python, and then I tried using the command prompt, and it worked. It turned out that if I deleted my idea folder in Pycharm, it would work with the new version!
I am a newbie to python. I am getting the below error in Kernel while opening jupyter notebook. Any ideas how I can resolve it? Installation of jupyter has been done via Anaconda3 - tried reinstalling and setting environment variables, but no luck so far. Any help would be greatly appreciated.

Works for Windows.
It looks like you had installed jupyter when there was an issue with its dependencies on Windows. See https://github.com/jupyterlab/jupyterlab/issues/7259 . I ran into the same error.
It should be fixed on conda now, so if you uninstall and reinstall jupyterlab from conda, it should not throw that error anymore.
I battled to get Jupyter working on my Windows 10 office computer for a number of hours. This was after installing Anaconda3. I had versions of Python 2 and 3 installed before. I was getting 'Kernel error' and also had various errors about 'win32api' and 'tornado'
I did many things but in the end main ones that, I think, helped are listed below -
On install, Anaconda3 created a data folder here -
C:\ProgramData\Anaconda3
I gave my user account access to write to this folder, I am not sure if it made a difference.
Elevated to admin, I copied two dll files as below -
pythoncom39.dll
pywintypes39.dll
From -
C:\ProgramData\Anaconda3\Lib\site-packages\pywin32_system32
To -
C:\windows\system32
At the 'Anaconda Prompt', a Windows cmd screen (which was added to my start menu) after the install, I did this -
(base) C:\>conda env create test-env
It created 'test-env' folder at C:\Users\{windows user name}\.conda\envs\test-env
(base) C:\>conda activate "C:\Users\{windows user name}\.conda\envs\test-env"
(test-env) C:\>
Once in this newly created environment, I tried various other things such as these -
conda install jupyter
conda install pywin32
python -m ipykernal install --user
Launching jupyter after loading and setting to this environment now works by using this command -
(test-env) C:\>jupyter notebook
When browser opens, select New>python 3 (ipykernel) from right hand menu to create new notebook.
If you have Python installed on your pc run from cmd or powershell:
pip install jupyterlab
Then you can start it with:
jupyter lab
The installation might have missed some steps which are fixed by post_install.
Go to yout venv's Script directory and run the command
python .\pywin32_postinstall.py -install
Make sure you are running the shell with Admin rights.
This error is sometimes as a result of the deleted environment that was created before. For Windows users, run the following code in cmd
python -m ipykernel install –user
Simply uninstall and install jupyter by first:
#Activate your environment in anaconda prompt (conda activate"path") and then type:-
conda uninstall jupyter
conda install jupyter
I installed jupyter on my macbook pro (10.10), using pip install jupyter, it completed sucessfully. However, when trying to run the
jupyter notebook
command - I get the following errors.

Simpler installation with Anaconda
An alternative to using pip is Anaconda or Miniconda.
It is great for installing scientific libraries such as Jupyter.
Anaconda
Anaconda is a full distribution of about 200 libraries including Jupyter. Just install it with given instruction as user (not root) and you should be good to go.
Miniconda
Miniconda is smaller. It includes Python and a few essential libraries. If Anconda seems to big, download and install Miniconda. Again, as user not as root.
Then, install Jupyter with:
conda install jupyter
In your case it is complaining to the log file. If you can specify it it should solve the problem, as now it is not finding it.
