I'm following Kx instructions on installing jupyterq, embedpy and kdb in Anaconda. This is where I want to get to - a Jupyter notebook where I enter q commands. However, when I launch Jupyter notebook from Anaconda Navigator, I'm only able to create a new Python 3 notebook.
How do I create a notebook which accepts q commands?
Checked so far:
I can launch q from ubuntu terminal, it's licensed
In Anaconda Navigator, base environment shows jupyterq, embedpy and kdb as installed
I see jupyterq_kernel.q and others in my ~/anaconda/q directory
EDIT: Meanwhile, I downloaded Jupyter kernel for kdb+ manually. Its install.sh apparently registered q kernel for Jupyter. I'm able to open a notebook with jupyter notebook from terminal.
The below is now redundant as the Conda package has been fixed, but is left for reference
You can follow the guide here http://www.enlistq.com/installing-kdb-jupyterq-and-embedpy-using-conda/ in order to add the kernel to Jupyter, it seems the package misses kernel.json
From the comments it appears this is or will be fixed, but given you've already installed everything, it is likely quicker to follow the relevant section of this tutorial (under "installing jupyterq")

Jupyter notebook is not opening kernels in my current environment. Running which jupyter in command line indicates the proper directory within the environment, my environment has nb_conda installed using conda_forge and also has ipykernel installed, I just updated conda to version 4.5.12. When I open jupyter notebook I am able to see a conda tab and my current environment shows up there but when I try to create a new notebook or change kernel within a notebook my current environment does not show up. When I run jupyter notebook in iterm (I am using zsh) I receive a message [nb_conda_kernels] enabled, 2 kernels found which is a problem because I have three kernels (root, an old environment, my current environment).
I've tried looking through different help forums on github and following the readme but I still haven't managed to get it to work. Any help would appreciated!
Maybe this does not work at all, because its a Mac, but maybe there is a way to open a jupyter notebook on a Mac? I tried the following command
jupyter notebook Manager.ipynb
and I got an error
Error executing Jupyter command 'notebook': [Errno 2] No such file or directory. Same with out 'notebook':
jupyter Manager.ipynb
Error executing Jupyter command 'Manager.ipynb': [Errno 2] No such file or directory
There is a file named Manager.ipynb in the current folder.
So is there a way to open that notebook on a Mac? Do I have to install some crazy stuff in order to make it work?
The problem I was facing was either a mis-installation of jupyter, or there is another application on Macs with the same name. However, (re)install it with this command
pip install --user jupyter
(a global pip install does not seem to work because of some Mac-nonsense, see here), and then it might work. Or install it in a virtual environment altogether.
This may or may not be helpful for you, but it's something to know and it's how I access the notebook on my mac.
When I installed Julia, it just came with the command line, I never got the icon to open the notebook or anything of that nature. I had too much trouble trying to install it so I just gave up on getting the icon or a direct link, but if you get Julia installed, you should be able to access the terminal version by entering
$ Julia
Or clicking on the Julia terminal icon, which will give you this:
And then you can just open the notebook by running the following:
using IJulia
IJulia.notebook()
Also if you're just starting with Julia don't forget you may have to add the package manager by typing using Pkg or adding it directly to your code.
This should open it in your default browser (there is no option to open it in a different browser or window). I'm not sure if this is useful but it's an option for those who have trouble installing it like I did.
I had Anaconda installed on Windows 8.1 and Jupyter notebook was working just fine with Julia and Python. I tried to install R kernel, however, it resulted in an error that some dependencies are needed, so I installed "m2w64-zlib" library in Anaconda then I installed R using this command "conda install -c r r-essentials" and I needed to update anaconda, so I did. After finishing all installations and updates Jupyter doesn't work. It just opens for a second and then switches off without opening the notebook in my browser.
I dont write code in "R" but Anaconda provides a few steps on how to get "R" working. Follow the steps in this link, Hope it helps:

It works now fine.
I uninstalled ipython
conda uninstall ipython
then installed Jupyter.
conda install jupyter
I installed tensorflow as described for Anaconda installation in the tensorflow.org. I could run the tensorflow in the Mac terminal just typing,
$ source activate tensorflow
$ python
import tensorflow as tf
But, when I run iPython notebook, it does not work by showing an error of no module named tensorflow. I felt like tensorflow was correctly installed but iPython notebook could not recognize it. Is there any way to fix it?
Please have a look at your path. When you do the command 'source activate tensorflow', your path may have changed. The example is following.
sherrie#sherrie-PC:~/tensorflow/tensorflow/examples/udacity$ source activate tensorflow
discarding /home/sherrie/anaconda2/bin from PATH
prepending /home/sherrie/anaconda2/envs/tensorflow/bin to PATH
Tensorflow is installed in the first path, instead of the second one.
The most important step comes. Open your directory of 'anaconda' --> find the 'envs' --> open 'tensorflow' --> copy all files in 'sitepack0ages' to 'anaconda/lib/python2.7/sitepack-ages'. Done.
My answer is based on this other answer: Trouble with TensorFlow in Jupyter Notebook. I had the exact same problem, and I solved it by doing this:
Once your environment is activated, run "which jupyter" and verify if the path returned points to the /bin folder under your environment, something like /my_environments_path/my_tensorflow_environment_name/bin/jupyter. If this is already the case, your scenario is different from the one I had;
Run "which pip" and/or "which pip3". Odds are, you are executing pip or pip3 from a different location, so Jupyter is not being installed inside your environment. In my case, Python version was 3.6, but pip3 was being called from a different location. I ran "pip install jupyter", since pip was inside the /bin folder in my environment. Once I called the correct pip, I checked again the "which jupyter" command, and this time Jupyter was under my environment and I could import Tensorflow inside my notebooks. If no pip's path points to your environment, install pip inside it by running "conda install pip".
I hope this works, along with the additional information on the link above.
I looked at this question, but it provides a Linux solution. I'm running Windows 7. I developed a working Vpython notebook in Jupyter on one machine (in my office). It runs Python 2 (Anaconda package), and it does everything I want it to do.
I have another Windows 7 machine in my classroom. It has Anaconda3, and when I try to run the same notebook file, I get a black, empty scene for the vpython code. Also, if I try to start a New notebook from the Home tab of Jupyter notebook, there is not a VPython selection in the classroom machine. On my office machine (with Anaconda, Python 2), there is a VPython notebook option in the New list of Home.
I have done conda update conda and conda update anaconda and pip install vpython --upgrade commands on both machines and get the same behavior.
I have tried creating a new notebook with vpython commands and get the same behavior.
Summary: VPython in a Jupyter notebook with Python 2 on Windows 7 works. VPython in a Jupyter notebook with Python 3 on Windows 7 fails.
Any reasonable solutions?
