I encountered an error while importing pdfplumber in Python3, indicating module chardet is missing. However, running pip list from the cmd confirms that the package is installed, version 3.0.4. Anyone had similar experience? Any resolution?

I have anaconda python3 kernel with pytorch and numpy installed in the environment. In jupyter notebook first line 'import torch' produces error.
I am using anaconda navigator to launch jupyter notebook and enter my environment and see pytorch is installed but not being imported. Tried various dir extensions 'from torch... import * but more error

I was able to add this to the end of my path to establish a 'backend ' for my notebook kernel. Thanks to Kris Stern!
-m ipykernel install --user
first get your kernel path with
(which python3)
then connect it using
sudo (your path)/anaconda3/bin/python3 -m ipykernel install --user

I recently made an update of IPython to 4.0.0 and installed Jupyter 4.0.6.
I wanted to use Ipython parallel, and after starting the engines in the notebook, I imported:
from IPython import parallel
And it fails:

ImportError: cannot import name rekey
So I tried:
pip install rekey
But no distribution were found.
Note that it fails the same way in the notebook, be it open with ipython notebook or jupyter notebook, and in the console.
Also note that there is a warning:
UserWarning: IPython.utils.jsonutil has moved to jupyter_client.jsonutil
But rekey does not exist in the module jupyter_client.jsonutil
Question: How can I have IPython parallel to work within Jupyter ?
What am I missing ?
I found the problem I think (at least it works):
First, I had to import ipyparallel instead of IPython.parallel
See here: http://jupyter.readthedocs.org/en/latest/migrating.html#imports
EDIT: I get this OSError, but the fix was apparently useless, and it works without. I still don't get why I had this error, though.
Then, I had another error, when starting the client:
OSError: Connection file '~/.ipython/profile_default/security/ipcontroller-client.json' not found.
You have attempted to connect to an IPython Cluster but no Controller could be found.
Please double-check your configuration and ensure that a cluster is running.
So I just copy the directory ~/.ipython/profile_default to ~/.jupyter/profile_default
And it works!
After installing pyql from the package source(according to its own wizard described in this file) on Ubuntu 14.04 into /usr/local/lib/python2.7/dist-packages/ folder, all tests finished with success. This folder includes all additional installed packages, which are accessible, from the python using native import command.
But, this specific installation python don’t see, and I cannot import anything from it.
Have you any idea, what I need to define in addition?
Thanks,
Yigal B.

After installing Ming 0.3.2, I tested the installation by running the following code:
>>> from ming.datastore import DataStore
>>> bind = DataStore('mongodb://localhost:27017/', database='tutorial')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: __init__() got an unexpected keyword argument 'database'
>>> ^D
I looked at the installation files and in the datastore.py file I found that the class's constructor did not contain a "database" argument.
class DataStore(object):
def __init__(self, bind, name, authenticate=None):
self.bind = bind
self.name = name
self._authenticate = authenticate
self._db = None
I then installed Ming 0.3.0 to look at the datastore.py file and found the DataStore class to match the documentation (it contained a database arg) and then tried that version where I encountered other complications.
I use easy_install to install Ming and I have a good install of mongodb and pymongo running. I run these on OS X Lion. Any advise on getting Ming running would be appreciated.
I think there may be a conflict with the newest version of pymongo and ming.
bind = DataStore('mongodb://localhost:27017/', name='test') gets me a bit further along, but I ended up just using pymongo by itself.
I've met the same issue. Here are the steps I've tried, and it works! Hopes it works for your environment too.
Uninstall the Ming 0.3.2 version by : pip uninstall Ming
Install 0.3.0 by: pip install -Iv http://downloads.sourceforge.net/project/merciless/0.3.0/Ming-0.3.0.tar.gz
Try the example on the Ming office website again. There will be another error
Traceback (most recent call last):

change the line 7 of "/home/me/work/deploy/test/local/lib/python2.7/site-packages/ming/session.py" to from bson.son import SON
try again. and it will works.
