I am trying to install Jupyter Notebook in macOS Mojave.
I have tryied with Anaconda but although anaconda3 is apparently well installed, with the correct path in my bash, I get:
$ jupyter notebook
-bash: jupyter: command not found
I have also tried with
python3 -m pip install --upgrade pip
python3 -m pip install jupyter
but after I try to open jupyter notebook I get this error:
$ jupyter notebook
Traceback (most recent call last):
File "/Users/danielavargasrobles/miniconda3/bin/jupyter-notebook", line 7, in <module>
from notebook.notebookapp import main

from nbformat import sign, validate as validate_nb, ValidationError
ModuleNotFoundError: No module named 'nbformat'
Does anyone have an idea of what is happening?
Thank you!
Did you installed jupyter inside your envirnoment ?
I had a similar issue, jupyter was launching because installed outside venv but not installed inside your envirnoment it will lead to nbformat issue.
conda activate your_env
conda install jupyter
should do the trick.

I have successfully installed Pillow:

but when i try to use it in pycharm got:

or using in Blender i got:

I am not a python lib installing pro...so obviously i made something wrong. But how do i fix that?
Maybe i have to say i am working on a M1 Macbook
looks like you may need to repoint your pycharm to your installed python interpreter.
go to command line and find out python interpreter path. On windows you can where python in your command line an it will give you where your python and packages are installed.. You could also activate python directly in command line and find paths from there. For example, open command line then;
python
press enter = activates python
within then you can do:
import sys
for x in sys.path: x
In pycharm make sure you point to path discovered from step 1 and select that to be your python interpreter within pycharm --- check out examples here https://www.jetbrains.com/help/pycharm/configuring-python-interpreter.html#add-existing-interpreter
Should work. Not sure about all the steps you took, but if you installed python with pycharm on top of your regular installation of python i would recommend :
finding all the paths from step 1
deleting python using system
checking if folders found from paths step still exist
if they do, delete those as well
start over just with one python installation
repoint to that in pycharm
first
pip uninstall PIL
after uninstall
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
or
brew install Pillow
I am getting the following error when trying run the example hello_world.py.
Traceback (most recent call last):
File "/usr/share/bcc/examples/hello_world.py", line 9, in <module>
from bcc import BPF
ImportError: cannot import name BPF
I installed bcc from source (link).
I also installed both the python bcc bindings packages, python-bcc and python3-bcc but no luck.
I am running Ubuntu 18.04 and kernel version 4.15.0-117-generic.
What am I missing here?
In ubuntu 20.04, I execute the following command to fix it.
sudo apt-get install bpfcc-tools linux-headers-$(uname -r)
I got the issue. I was using the pyenv to manage my python versions, so the python was looking files in the wrong locations.
$ python -c 'import site; print(site.getsitepackages())'
['/home/sagar/.pyenv/versions/3.6.6/lib/python3.6/site-packages']
I tried with a python3 command, which was not installed by pyenv and I don't get the above error.
I encountered an import problem by PyAudio.
I have a winodws 10, 64 bit, and use Anaconda and Spyder IDE with python 3.7.
I installed PyAudio in Ananconda, ran as administrator, with these commands :
cd
conda install -c conda-forge PyAudio
The installation ran without any problems.
I then restarted both Anaconda and SPYDER. PyAudio now shows up in Anaconda's list of installed packages.
When I try to import Pyaudio in Spyder (IPython console), I encounter this error message :
[1]: import pyaudio
Could not import the PyAudio C module '_portaudio'.
Traceback (most recent call last):
File "", line 1, in
import pyaudio
File "C:\ProgramData\Anaconda3\lib\site-packages\pyaudio.py", line 116, in
import _portaudio as pa
ImportError: DLL load failed: The specified module could not be found.
I tried to fix it by answers to similar ImportError message issued, while other users tried to import other packages like SKlearn ... , but with no success.
Your problem (and mine) are the same. The issue is, unfortunately, the version of python you're running (in tandem with your OS).
Check out this link:
https://people.csail.mit.edu/hubert/pyaudio/#:~:text=Note%3A%20As%20of%20this%20update,4.
Under the INSTALLATION section in the link for WINDOWS, PyAudio's latest version (0.2.11) is compatible with Python versions: 2.7, 3.4, 3.5, 3.6.
My current python is 3.8.5, so you (and I) could never use PyAudio unless they added compatibilities or we revert to an above python version.
I tried to install portaudio using
conda install portaudio
but it seems like it didn't work as it should be. However,
conda install -c anaconda portaudio
solved the problem.
see the official anaconda page
I'm both updating and installing packages/libaries, but are only able to use them through the Python3.6 console.

It seems that scikit-learn has not been built correctly.
If you have installed scikit-learn from source, please do not forget
to build the package before using it: run `python setup.py install` or
`make` in the source directory.
It appears that you are importing a local scikit-learn source tree. For
this, you need to have an inplace install. Maybe you are in the source
directory and you need to try from another location.

If you've installed a package using pip3.6, make sure that your kernel version for your notebook is 3.6 -- if it's (say) 3.7, then it won't work, because each version of Python has its own separate set of installed modules.
I imported the notebook, and forgot to change Kernel Python3.6. It was still on Python3. Changed notebook to 3.6, and the it used the updated libary's-
When you run pip on PythonAnywhere, outside virtual environment, it installs packages for python2. The latest version of scikit-learn to work with python2 is 0.20.4. So, install it with pip install scikit-learn==0.20.4
You tried to install 0.22.1 with python2.
I am having this error with my IPython version on Redhat.

Could you please help me to resolve it?
According to this question, try:
conda config --add channels conda-forge
conda install backports.shutil_get_terminal_size
I got the same question as yours. I solve it by using pip install -U ipython to update IPython and it workes. Hope it helps!
If you don't want to use conda, try below.
pip install https://github.com/chrippa/backports.shutil_get_terminal_size/archive/159e269450dbf37c3a837f6ea7e628d59acbb96a.zip
None of the uninstalling/reinstalling stuff worked for me. What eventually worked for me was suggested by #ternus in a comment above: open up (on linux) /usr/local/lib/python2.7/dist-packages/IPython/utils/terminal.py and change the line
from backports.shutil_get_terminal_size import get_terminal_size as _get_terminal_size
to
from shutil_backports import get_terminal_size as _get_terminal_size
Reference: https://github.com/ipython/ipython/issues/9656
Author: https://github.com/ihincks
I follow this post
IPython console can't locate "backports.shutil_get_terminal_size" and won't load
to change /usr/lib/python2.7/site-packages/IPython/utils/terminal.py and it works for me
For me this worked (on Debian):
apt-get install python-ipython
