zmq: Can not launch jupyter notebook #3435

Yumin-Sun-00 · 2018-03-16T21:03:54Z

Hi,

conda activate base
jupyter notebook

Gives me this message:

Traceback (most recent call last):

I did pip install pyzmq --install-option="--zmq=bundled", but not works.
I did conda install -c anaconda pyzmq, also not works.

The text was updated successfully, but these errors were encountered:

Unless @minrk knows better, it looks like your installed package has got corrupted (possibly by mixing conda and pip usage). If so, probably the easiest thing is to remove and reinstall Anaconda.

Yumin-Sun-00 · 2018-03-28T13:56:19Z

Yeah, right now I could only start jupyter under the virtual environment installed with anaconda full meta package. Base and global is not able to use jupyter.

By the way, I think conda mix a lot of things.

Like if I install opencv globally and then install a different version in virtual environment, my opencv global will gives me segmentation fault, but it could be used in Base. Further, under the virtual env with diff. opencv, although everything installed, I mean you could fins cv2.so, and libopencv, but you have to cd the PATH to that python site packages, otherwise you are still using Base version opencv. The conda totally not easy my installation, just bring a lot of mess to my my setup work.

Could I ask you update your documentation with more detail instructions for using conda, if the conda mix so many things together.

harsh23tyagi · 2018-06-19T21:18:06Z

Hey , use the following:
pip uninstall pyzmq
pip install pyzmq

The thing with conda is that it has a lot of conflicts, you might be having a conflict. Using simple pip command would help you to remove those conflicts. I mean it worked for me. I hope it helps

info85 · 2018-12-16T02:57:24Z

I have the same issue, I am no able to launch Jupyter notebook. It errors out.
I tried a) pip uninstall pyzmq - it errors with access denied.
I am new and I am afraid, I am in trouble please help. I may have to manually uninstall everything and then reinstall.

This helped me solve the problem! Many thanks!

AdamTarnawski · 2019-01-27T20:05:40Z

You should be using Anaconda prompt, which is installed by default with Anaconda. And the command should be here:
conda uninstall pyzmq and then conda install pyzmq.

It worked for me. When I installed Jupyter Notebooks to a new environment in Anaconda, it updated some other packages. I needed to uninstall pyzmq from Anaconda and reinstall it. The packages were downgraded and now it works fine.

MikeB2012 · 2019-02-12T14:23:21Z

I have installed Anaconda on an SSD drive. Launching Anaconda Navigator and then VSCode or Spyder was fine. Jupyter Notebook wouldn't launch and gave the same error as the OP.
Using 'conda uninstall pyzmq' uninstalled pyzmq and everything else in Navigator except VS Code. That was not expected. I then opened Anaconda Navigator and reinstalled Jupyter Notebook and got the same error as before. ie.

Same problem

gauravkoradiya · 2019-07-21T10:25:41Z

you resolve my issue. thank you

fpmarcos · 2019-08-29T18:27:37Z

Get pip here: https://bootstrap.pypa.io/get-pip.py
Run the following command: python get-pip.py

You can verify that Pip was installed correctly by opening a command prompt and entering the following command: pip -V

Now that Pip is installed and configured, you can begin using it:

pip uninstall pyzmq
pip uninstall jsonschema
pip install pyzmq
pip install jsonschema

Its works for me!

помогите пл

KushnirAndrey · 2019-12-10T10:54:38Z

ты внутри backend.py пытаешься импортировать backend.py)
И в backend у тебя в принципе нет obj

Возможно ты хочешь сделать: from frontend import obj as calculator

jenjajenjaBot · 2019-12-10T10:58:35Z

KushnirAndrey · 2019-12-10T10:58:39Z

KushnirAndrey · 2019-12-10T18:47:39Z

Не совсем понимаю откуда и зачем тебе str_operation...

BACKEND:

from frontend import obj as calculator

def run():
try:
first = float(input('->>'))
operation = input('operation->>')
second = float(input('->>'))
result = calculator[operation](first, second)
print(result)
except Exception as e:
print(e)
pass

if name == "main":
run()

FRONTEND:

def add(a, b):
return a + b

def sub(a, b):
return a - b

def div(a, b):
try:
return a / b
except ZeroDivisionError as e:
return e

def mul(a, b):
return a * b

obj = {'+': add,
'-': sub,
'/': div,
'*': mul
}

Check the environment.
you probably have more than one version installed of pyzmq
just uninstall the later version
only use
pip uninstall pyzmq
