I was doing my Logistic Regression with a Neural Network mindset when my submit button disappeared. I followed some instructions that told me to delete the notebook and that a fresh notebook would come back later, but the notebook completely disappeared. Every time I try to access it, I get a 404. I would much appreciate some help
If you deleted jupyter so try to install it from Anaconda Prompt with below command.
pip install ipykernel or conda install ipykernel
Once its completed then run below command..
python -m ipykernel install --user --name=NewEnv
Now run jupyter notebook from anaconda prompt it will work fine..

Problem:
When I try running code by line (f10) with VS Code, "ipykernel setup required for this feature" message pops up.
What I've tried:
Using Anaconda Prompt: "conda install ipykernel", "conda install -c conda-forge ipykernel"
-When I tried this, the prompt said "conda-forge:: ipykernel-6.4.1-py38h595 --> pkgs/main:: ipykernel-6.2.0-py38haa95532_1"
Doesn't it mean I already install ipykernel v.6.20 or higher?
After I tried this I checked Jupyter --Version it said ipykernel 5.3.2
Other specs are qualified. (VS Code, Jupyter, Anaconda versions etc,)
Using Terminal (in VS Code): "pip install ipykernel"
Reinstalling all of add-ins such as Python for VS, Python, Anaconda, Jupyterlab, VS Code
Updating ExecutionPolicy: CurrentUser-RemoteSigned, LocalMachins-AllSigned, others Undefined.
+) Created virtual-env named envi which is conda env. In VS Code I selected this interpreter and also reloaded all windows.
As I understand, Conda install Ipkkernel > Reload is what pop-up msg required.
This is what I'm going through now.. I just got interested in Python and now I cannot doing anything..
I had the same problem. It seems there was a problem with the version of ipython or ipykernel since I managed to fix it by running the following commands in conda environment:
pip install --upgrade ipython
pip install --upgrade ipykernel
Don't know which of the two was the problem but I was able to use the jupyter notebook line-by-line feature after this.
In the official jupyter labs installation guide, it says to install jupyter labs with pip install jupyterlab and then launch with jupyter-lab.
However, what I did was try the first installation method, and when the jupyter-lab command to open didn't work, I tried installing again with python -m pip install jupyterlab.
Now the jupyter-lab command that is listed still isn't recognized, but after playing around, I found that python -m jupyterlab opens jupyter labs for me.
Why is this?
Should I be concerned that I messed anything up, should I just keep using the command that I found, or try to fix my installation so that the official jupyer-lab opens the program up?
Thanks
I hope everyone is doing good.
I installed Python a couple of days ago and then I install Anaconda3 2019.
Here is the screenshot of my programs installed on my system.
Now when I am trying to work on Jupyter, it is not opening. I tried to open Jupyter Notebook directly from the start (It showed a terminal opening and closing but after that, Localhost couldn't start). Later I tried through Anaconda Prompt and it gives me this Error.
conda list command shows that Jupyter library is present but I don't know where the problem lies.
These are the paths Environment variable has:
I'm a newbie and playing with python, Jupyter. I will appreciate it if anyone can help me to solve this issue I'm currently facing.
Thanks & Regards

Running Command conda install nb_conda produced this error:
Please follow the below steps:
conda activate <env_name>
conda install ipykernel
ipython kernel install --name <env_name> --user
If you are working on base environment, you can specify env_name as base.
Try running jupyter notebook using the command jupyter notebook
Hope this helps.
Go to your anaconda prompt and type the command conda install nb_conda.
Let this install and then try running the command jupyter notebook.
Let me know if this helps.
I am a beginner in Anaconda. I am using jupyter notebook. Tensorflow is working on anaconda prompt but not opening in jupyter notebook. how to resolve this problem. Please help me out. I am a beginner.
enter image description here
You created an environment with tensorflow but you didn't install jupyter-notebook in it. You need to install the notebook in the same environment where you installed tensorflow:
On Windows from the anaconda command line you need to activate the environment where you installed tensoflow (in your case from the picture you posted it seems to be called tensorflow). Then install it there. Execute the following commands in the anaconda command line to achieve this and then start the notebook in tensorflow's environment
(base) C:\Users\usr>activate tensorflow
(tensorflow) C:\Users\usr>conda install jupyter
(tensorflow) C:\Users\usr>jupyter-notebook
This should solve your problem.
The python kernel in Jupyter notebook points to the root kernel. If you need a specific environment to be displayed in your Jupyter notebook, do the following
# Creating a custom environment in anaconda prompt with python 3.6
(base)C:\>conda create -n MyEnvironment python=3.6
(base)C:\>activate MyEnvironment
# Install your custom pacakges like tensorflow etc
(MyEnvironment)C:\>pip install tensorflow
(MyEnvironment)C:\>python -m ipykernel install --name MyEnvironment
(MyEnvironment)C:\>jupyter notebook
Now you should be able to see both root kernal and MyEnvironment kernel version in Jupyter notebook
I hope this question is not redundant, but I couldn’t find a solution on the internet so far. I’ve followed the github guide (https://github.com/fastai/fastai) to install the fastai library on my Anaconda environment. I want to use this library to tackle the ML course and solve other Kaggle competitions with it.
As per below, I’m opening my conda environment, selecting fastai and opening Jupyter Notebook:
When trying to run the packages in Jupyter, I still get an Import Error with No module named ‘fastai’. Any suggestions on what I’m doing wrong?
Had same issue. It looks like the problem is with "softlinks" fastai which are not working on Windows.
I fixed it with replacing that soflinks with real module fastai from root of repository. Just copied it to courses\dl1, courses\dl2, courses\dm1 and tutorials folders.
Prerry dirty. But works. Let me know how to fix it without copying.
Add a cell to the beginning of the notebook, !python -m pip install git+https://github.com/fastai/fastai.git
Edit:
Now that fastai is 1.0 and on pip, you probably just want to !python -m pip install fastai.
I prefer the !python -m pip syntax over just calling pip when mixing anaconda and pip, but it probably just reflects my system's python being messed up.
I had trouble making fastai_v1 work in jupyter lab, however it was working on the terminal. So the problem was with the virtual environment not being selected in the jupyter lab when it was launched.
I used the below code to make it work. Replace 'myenv' with your virtual environment name.
source activate myevn
python -m ipykernel install --user --name myenv --display-name "Python (myenv)"
jupyter lab
