Jupyter Labs ModuleNotFoundError: No module named 'traitlets.utils.descriptions'

I would like to install jupyter labs on my linux system. I have python3.9 installed so I run pip install jupyterlab as per official documentation.
After the download is finnished, I get the following error:
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
notebook 6.3.0 requires nbconvert==6.0.7, but you have nbconvert 6.5.0 which is incompatible.
notebook 6.3.0 requires nbformat==5.1.3, but you have nbformat 5.4.0 which is incompatible.
notebook 6.3.0 requires traitlets==4.3.3, but you have traitlets 5.3.0 which is incompatible.
Weird, but I have tried intalling all of these manually afterwards using pip install nbformat==5.1.3 and so on...
After the installation, I run jupyter lab, and the following error appers:

from traitlets.utils.descriptions import describe
ModuleNotFoundError: No module named 'traitlets.utils.descriptions'
I have tried installing traitlets, but indeed when I run:
import traitlets
traitlets.utils.descriptions
I get:
AttributeError: module 'traitlets.utils' has no attribute 'descriptions'
Maybe this is the wrong version of the module? Which one should I install then?

Error importing tensorflow in Python 3 on Ubuntu 16.04 SyntaxError: l.append("%s=%s" % (attr, `value`))

I have python 3.5 installed on my Linux Mint (Ubuntu 16.04 Xenial)
I also had installed protobuf installed using pip3 install protobuf
I installed tensorflow using pip3 install tensorflow
Then I tried to import tensorflow in python 3 it failed with error presented below:

Consulting through many questions posted on SO and other forums, I tried uninstalling protobuf then I encountered following error.

At the moment I'm just a beginner for all of this. I don't why protobuf is required why do all this hassle? I just wanted to get tensorflow installed on my system and try to learn something.

I was also facing the same problem. The problem I think is this is using pandas from system(apt-get) repository which is not compatible with other libraries. Updating pandas do the trick.
pip3 install --upgrade pandas
Also in your case, if only doing above fails, you can also try to reinstall tensorflow and protobuf with upgrade option.
pip3 install --upgrade protobuf
pip3 install --upgrade tensorflow

I just installed TensorFlow on my system today (Ubuntu 16.04 LTS) using VirtualEnv.
Did you run$ sudo apt-get install python3-pip python3-dev
If so, then try $ pip3 install -upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.4.0-cp35-cp35m-linux_x86_64.whl
Worst comes to worse, you could simply uninstall TensorFlow using $ sudo pip3 uninstall tensorflow and then try reinstalling to see if it corrects any errors.

Tensorflow on OSX: Failed to load the native TensorFlow runtime (No module named pywrap_tensorflow_internal)

I'm trying to install Tensorflow (r1.2) on my MacBook (OSX 10.12.5).
The installation works, but I'm getting errors, when I try to import TF in python.

I'm working in a virtualenv (using virtualenvwrapper) with up-tp-date packages
python 2.7.10
pip 9.0.1
numpy 1.13.1
wheel 0.29.0
six 1.10.0
I tried to install the default pip package (no GPU support) using pip install tensorflow, first.
Afterwards I also tried to install tensorflow from source following the installation tutorial, without CUDA support (configure script said No CUDA support will be enabled for TensorFlow). Building and installing reported no errors, but I got the same error when I tried to import tensorflow.
Related questions/answers pointed out problems with CUDA or missing Windows dll files, which do not seem to fit my problem.
Any help is welcome. Thanks in advance.

I have the same problem.i did this
First
pip uninstall tensorflow
Download this tensorflow wheel file
Now install this using(in same Directory)
pip install tensorflow-1.6.0-cp36-cp36m-win_amd64.whl

My answer is same to yours.
I deleted the tensorflow with "rm -r ~/tensorflow ",
and finally it working when I have reinstalled it
The detail is here:https://www.tensorflow.org/install/install_mac#CommonInstallationProblems

Any thoughts?

This does look like a protobuf library versioning error. There's a long thread on similar issues here:
https://github.com/tensorflow/tensorflow/issues/11
Towards the end there are some suggested solutions that might help.

I succeed in running TensorFlow 0.7 on a manjaro linux laptop using cuda acceleration by running python with optirun:
$optirun python
However, I had problem with protobuf and I had to uninstall/reinstall previous version of protobuf and tensorflow with pip. http://bit.ly/1RHApU5

This is because of protobuf version conflict:
for me i had python-protobuf v2.6.1 installed from apt-get package manager
and while installing tensorflow it installed protobuf v3.3.0 from pip manager
so i uninstalled both:
sudo pip uninstall protobuf
sudo apt-get remove python-protobuf
Reinstalled using pip and it solved the issue!!!
sudo pip install protobuf
Hope this helps..

Unable to import ssl on linux

When I try to import ssl on any Python version I get
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.5/ssl.py", line 98, in <module>
import _ssl # if we can't import it, let the error propagate
ImportError: /lib/x86_64-linux-gnu/libssl.so.1.0.0: symbol X509_chain_up_ref, version
OPENSSL_1.0.2 not defined in file libcrypto.so.1.0.0 with link time reference
I have compiled Python 3.5 myself with libssl-dev version 1.0.2. According to aptitude I have libssl1.0.0.0 version 1.0.2 and openssl version 1.0.2 installed.
It seems to be a problem with the different version of libssl, openssl and libssl-dev but I have installed an reinstalled the newest version of all of them via the Package manager.
Im using Ubuntu 15.10 64-bit
