pyzmq falta al ejecutar el cuaderno ipython

Question

Puedo ejecutar iPython, pero cuando intento iniciar una notebook, aparece el siguiente error:

~ ipython notebook

ImportError: IPython.html requires pyzmq >= 2.1.11

Pero, por lo que puedo ver, ya tengo el paquete pyzmq instalado.

~ pip install pyzmq
Requirement already satisfied (use --upgrade to upgrade): pyzmq in /Library/Python/2.7/site-packages/pyzmq-14.3.1-py2.7-macosx-10.6-intel.egg
Cleaning up...

Answer 1

Arg. La instalación de ipython es un poco idiosincrásica. Esto es lo que tuve que hacer para resolver esto:

$ pip uninstall ipython
$ pip install "ipython[all]"

El problema es que los portátiles tienen su propio conjunto de dependencias, que no están instaladas con pip install ipython . Sin embargo, al haber instalado ipython , pip no ve la necesidad de agregar nada si luego prueba el formulario [all] .

Como se menciona en los comentarios para algunos shells (por ejemplo, zsh), es necesario escapar o citar los corchetes (la pip install ipython/[all/] también funcionaría).

Answer 2

Para mí (Ubuntu 14.04.2) funcionó la instalación de synaptic package manager: el paquete se llama python3-zmq, con este paquete se instalará libzmq3.

Después de eso, compruebe si pyzmq está instalado correctamente:

pip list

Luego instalé ipython:

pip install "ipython[all]"

Answer 3

Utilizando

ipython2.7 notebook

En lugar de

ipython notebook

¿El truco para mí?
