When using an Anaconda environment, I can't start Jupyter to work in a notebook. I can do so without the environment, but I need to be able to use the environment. Here's what I do and the errors I get:

ben@ben-K60IJ:~/surveillance_sound_classifier/surveillance_sound_classifier$ source activate EECS352 discarding /home/ben/anaconda/bin from PATH prepending /home/ben/anaconda/envs/EECS352/bin to PATH (EECS352)ben@ben-K60IJ:~/surveillance_sound_classifier/surveillance_sound_classifier$ jupyter notebook Traceback (most recent call last): File "/home/ben/anaconda/envs/EECS352/bin/jupyter-notebook", line 4, in <module> import notebook.notebookapp File "/home/ben/anaconda/envs/EECS352/lib/python2.7/site-packages/notebook/notebookapp.py", line 61, in <module> from .services.contents.manager import ContentsManager File "/home/ben/anaconda/envs/EECS352/lib/python2.7/site-packages/notebook/services/contents/manager.py", line 16, in <module> from nbformat import sign, validate, ValidationError File "/home/ben/anaconda/envs/EECS352/lib/python2.7/site-packages/nbformat/__init__.py", line 33, in <module> from .validator import validate, ValidationError File "/home/ben/anaconda/envs/EECS352/lib/python2.7/site-packages/nbformat/validator.py", line 21, in <module> raise ImportError(str(e) + verbose_msg) ImportError: No module named functools32 Jupyter notebook format depends on the jsonschema package: Please install it first.

Yes, I've done pip install jsonschema and conda install jsonschema AND pip install functools32 and conda install functools32 from within the EECS352 environment to no avail; I arrive at an almost identical error, except this time, functools32 is replaced with _version.

I've reinstalled Anaconda, updated all its packages, created a new environment in the same way I created this one, and still I get this error. I'm using Ubuntu 15.10 32-bit. I used to be able to use this environment with no problems until roughly a week ago.

If this is a duplicate, please point me to the original; however, I haven't yet found anything that seems really relevant. The only thing that might be relevant is that this error did pop up after I modified some .conf file because I was having issues updating my computer's software using sudo apt-get upgrade. I don't recall what I had done and to which file, but if it's likely the source of this issue, I can spend some time trying to track it down. Please let me know if I should spend my time to do this, and I will.

I think I have a solution.

I did may things, regenerated my env (anaconda env) from another computer where it worked, but no success.

What I think that nailed it is upgrading jsonschema to 2.5.1

Here are my steps from "bad" jupyter env to working jupyter env.

Good luck and come back if it doesn't work, I will post the notebook* relevant versions.

i also got the same error and none of the above mentioned procedures worked for me so i've checked the documentation of anaconda and found something useful

conda install -c conda-forge/label/cf201901 jsonschema

conda install jupyter

jupyter notebook

this worked for me,thanks to anaconda documentation

Re-install jsonschema solve the problem in my case:

$ pip uninstall jsonschema ... $ pip install jsonschema ...

If any of the above mentioned solution didn't work then try this in your anaconda prompt: First run conda update -n root conda so you have the latest conda version installed. Then run conda update --all This will update all packages in the current environment to the latest version. Even after installing jsonschema, your Jupyter Notebook might not run and give you the error:

Jupyter notebook format depends on the jsonschema package:

Please install it first

Then I suggest you to run the given two commands. It will solve your issue as it solved mine.

Try this from the terminal:

pip install ipython[notebook]

It worked for me, let me know if the problem still exists.

I had the same problem.

I solved it by running this command

conda install -c anaconda jsonschema

I solved it by just uninstalling and reinstalling python 3.7

upgrade it using

conda install -c conda-forge jsonschema

Try this from terminal, it worked to me: 

pip install --upgrade pyrsistent
