Jupyter returns this, but when I try to install astropy using terminal, all of the requirements return as satisfied.

To date I have been using Jupyter Notebook to run R and sometimes Python code. I have also been using RStudio at times. Recently, while using RStudio, I was prompted to install some package (cannot exactly remember). At any rate, I installed this package. Dont know if only coincidence, but trying to run R in the notebook resulted in kernel not connecting. I found the same issue with Python, the Python kernel is also not connecting anymore.
Executing the below, I get;
(base) C:\WINDOWS\system32>jupyter kernelspec list
Available kernels:
ir C:\Users\Admin\AppData\Roaming\jupyter\kernels\ir
python3 C:\Users\Admin\anaconda3\share\jupyter\kernels\python3
How do I get Jupyter Notebook's kernels to work again.
Executing IRkernel::installspec() in R via Anaconda CMD prompt have resolved the issue. Note for others with this issue, you may be prompted to run install.packages(“rlang”) before.
Installed JupyterLab using below commands and tried to read data using spark but in cmd it says The system cannot find the path specified.
Installed Jupyter using pip install pyspark==2.3.1
pip install jupyterlab
jupyter-lab
As i am new to pyspark cannot able to figure out what exact the issue is
Pleasehelp me
I am trying to work with Apache Three and jupyter, in Mac OS High Sierra. While I am installing everything appropriately with:
pip3 install --user toree
when I am trying to install anything with jupyter toree install I end up with a message as simple as: Error executing Jupyter command 'toree': [Errno 2] No such file or directory
I have googled the message, end up with abstract searches regarding errors not including toree itself, so how is that solved?
I recently began using julia, and I would like to use in with IPython Notebook/Jupyter.
So, I installed julia using MacPorts, i.e. sudo port install julia. Following the installation instructions here: https://github.com/JuliaLang/IJulia.jl
After the prompt, I used "Pkg.add("IJulia") to install IJulia.
However, I cannot use Julia with IPython notebook. After opening the notebook with
ipython notebook --profile=julia
the kernel for the julia notebook dies instantly and cannot be restarted.
The error on the Terminal shows:
[I 19:03:19.410 NotebookApp] KernelRestarter: restarting kernel (1/5)
WARNING:root:kernel dc00ae3a-8fa6-4d01-a802-f7845a16a9ba restarted

while loading /Users/NAME/.julia/v0.3/IJulia/src/kernel.jl, in expression starting on line 6
I suspect I have installed IJulia incorrectly? How can I solve this?
(The version of julia is julia version 0.3.11. The version of python is Python 2.7.10. The version of ipython is 4.0.0.)
The current stable version of Julia is v0.4.0.
You should download it directly from the Julia homepage (.dmg):
http://julialang.org/downloads/
Having done that, run it and do Pkg.add("IJulia") again.
Then from within Julia do
using IJulia
notebook()
Note that the Jupyter Notebook (the new name for what used to be the IPython Notebook) is run as
jupyter notebook
The --profile julia is no longer necessary and should be removed.
Furthermore, this (jupyter notebook) will only work if you had a previous installation of Jupyter, which seems to be the case. In this case, I suggest you upgrade it with conda, if you installed Anaconda, or with pip.)
I have IPython and IPython Notbook installed and am working my way through the IHaskell installation instructions. I have all the IHaskell prerequisites installed, but before I commit to the final step of installing IHaskell itself with
cabal install ihaskell --reorder-goals
I want to confirm one — perhaps obvious — thing: Will I still be able to use Python Notebooks? The instructions following the step above seem to say that simply entering
ipython notebook
will run Haskell rather than Python, as if Haskell has replaced Python in IPython Notebooks. Is this the case? How do I specify whether I want to run Haskell or Python in a notebook, or in IPython itself for that matter? Can I switch freely between the two?
OS X 10.10.4; Xcode 6.4; CLT: 6.4.0.0.1; Clang: 6.1; Haskell Platform 7.10.2-a. Python 2.7.10 (Homebrew). Using Homebrew in general, but, following what appears to be Homebrew's recommendation, not for Haskell.
Like other kernels, IHaskell can be added to IPython/Jupyter without interfering with other kernels. Once added Notebooks will recognize the language used in (suitably tagged) notebooks and will add an entry to the 'New' notebook menu that allows selection of the language to be used for new notebooks.
Each kernel will have its own command for adding itself to IPython/Jupyter. For IHaskell this is simply
ihaskell install
