I'm using Python 3.5.2 on Ubuntu 16.04.
I've installed sklearn using..
sudo apt install python-sklearn
and mlxtend using...
sudo pip3 install mlxtend
I'm trying to run the basic Iris example found on the Internet, but I am getting an error as soon as I try to import plot_decision_regions from mlxtend.plotting:
from mlxtend.plotting import plot_decision_regions
Traceback (most recent call last):
File "scripts/machine.learning.py", line 6, in <module>
from mlxtend.plotting import plot_decision_regions

from .heatmap import heatmap

raise AssertionError(f'len(row_names) (got {len(row_names)})'
^
SyntaxError: invalid syntax
I had the same error, just upgrade to python3.7 the real error is
python 3.5 does not support f prefix
upgrade using conda
conda install -c anaconda python=3.7
and then update all depencies
conda update --all
I'm not seeing the same error as you, but try remove legend=range(105, 150) from plot_decision_regions i.e.
plot_decision_regions(x_combined, y_combined, clf=tree)
I'm using the latest current sklearn, i.e.
import sklearn
sklearn.__version__
'0.21.3'
Perhaps remove that version
sudo apt-get remove python-sklearn
Then install via pip, i.e.
pip3 install scikit-learn

Cannot install ta-lib on MacOS.
pip install ta-lib
How to install it?
Try:
brew install ta-lib
pip install ta-lib
Source: https://github.com/enigmampc/catalyst/issues/187#issuecomment-374552524
Faced the issue on Big sur again
The situation:
brew install ta-lib was successful and so was pip install TA-Lib
version 0.4.19
On console:
>>> import talib
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'talib'`
Solution: Installing from source worked for me, here are the steps
Install ta-lib using homebrew brew install ta-lib, this is required
Download the source from TALIB_SOURCE
untar/unzip the download ( tar -xvzf mrjbq7-ta-lib-TA_Lib-0.4.19-19-g5eb3fa4.tar.gz
cd into the folder and run:
pip install -r requirements.txt
python setup.py install
import talib should be working now
Here is the solution that usually works for me. In the file you are trying to import the module copy and paste the following code and run it. Then you will be ready to go.
from pip._internal import main as install
install(["install","ta-lib"])
Hope this will work for you, Good luck.
I'm on Ubuntu 18.04 and using python 2.6.6 that I installed from tgz package from here https://www.python.org/downloads/release/python-266/ using this instruction: https://askubuntu.com/questions/25961/how-do-i-install-a-tar-gz-or-tar-bz2-file. I'm trying to install pip using this instruction https://pip.pypa.io/en/latest/installing/
but when I run
python get-pip.py
I got errors about dependencies:
Traceback (most recent call last): File "get-pip.py", line 28, in
import tempfile File "/usr/local/lib/python2.6/tempfile.py", line 34, in
from random import Random as _Random File "/usr/local/lib/python2.6/random.py", line 47, in
from os import urandom as _urandom ImportError: cannot import name urandom
First it was cannot import name zlib. I installed zlib and now I got about urandom so I guess there might be more that I don't have installed. What's the best way to deal with it?
You could try sudo. If that doesn't work, try stating the python version.
$ sudo python2.6 get-pip.py
I think it is better to install via OS package:
apt install python python-pip python-setuptools
I followed the link here to install fastai library using pip install git+https://github.com/fastai/fastai.git
It gave me the following error message. These messages keep the same even I installed Pytorch successfully using conda install pytorch-cpu -c pytorch
and pip3 install torchvision. What can be the reason?
Collecting torch<0.4 (from fastai==0.7.0)

RuntimeError: PyTorch does not currently provide packages for PyPI (see status at https://github.com/pytorch/pytorch/issues/566).

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\shuxi\AppData\Local\Temp\pip-install-7sjptuad\torch\
To fix this, do:
$ pip install --upgrade git+https://github.com/fastai/fastai.git
OR
$ pip install --no-cache-dir git+https://github.com/fastai/fastai.git
Your command probably failed because you have installed a old version of torch (0.1.2) some time ago. pip was not supported for torch install for that version and pip instead redirected the user to open pytorch.org in the browser. In your case, pip is reusing this cached package. --upgrade forces pip to choose latest version of all depending packages.
I got the message
You are using pip version 8.0.2, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
When I try to install a package through pip.
I followed the instruction and upgrade pip with pip install --upgrade pip. Now I'm getting an error with pip, even with pip --version to check the version of pip.

ImportError: Entry point ('console_scripts', 'pip') not found
I've searched online and found some similar issues like, this, this and this. but none of the solutions worked for me.
I think it might be I have multiple version of pip on my Mac, how can I clean it up and get the latest version installed, please?
Thank you.
Manually removed all pip repositories in /usr/local/bin/. (not sure if it's necessary.)
Then reinstall pip following the instructions here.
To install pip, securely download get-pip.py.
Then run the following:
python get-pip.py
FYI, easy-install pip doesn't work.
I am running python 2.7 under ubuntu 12.04. I'm trying to install spyder using pip but get the error message:
error: invalid command 'egg_info'
Command python setup.py egg_info failed with error code 1
I looked at other posts, which recommended I install distribute. But I get the same error message when installing distribute using pip
When I try to upgrade scipy or install spyder with pip I get the following message:
Command python setup.py egg_info failed with error code 1

I'm new to python, pip and ubuntu, which makes this more difficult. Thanks in advance.
You can install spyder by simply typing following command in terminal
sudo apt-get install spyder
The another way is :
Open "Ubuntu Software Center" search for spyder and click on "Install."
(Spyder dev here) Maybe your problem is because Ubuntu 12.04 has an outdated version of pip. You can update it using sudo easy_install pip, and then try again.
You can also try to use easy_install instead of pip to install Spyder. Just run the command sudo easy_install spyder to see if that works.
Notes:
If these solutions don't work for you but you still want to try the latest Spyder (and other scientific packages like scipy or pandas), you'll have a much better time by installing a Python scientific distribution like Anaconda.
Don't try to install scipy with pip. That's not so easy as installing Spyder.
