I forked the scikit-learn repository, added a file that I need and downloaded the repository. I am not sure how to use this custom library. I cd'ed to the scikit-learn-master folder and tried to use it but it throws errors. So after reading the errors I installed it using python3 setup.py install. There were two setup.py files. One in the scikit-learn-master folder and sklearn folder so I ran python3 setup.py install at both these locations. They threw some warnings but no errors. I opened the python terminal in the scikit-learn-master folder and used import sklearn which returns the following -

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.
If you have used an installer, please check that it is suited for your
Python version, your operating system and your platform.
I am not sure how to proceed. Is there anything I am missing?
It appears the module has not been built correctly. And so it shows importError for check_build.
Before installing the module using pip, make sure you have installed all of the dependencies. On the README file, the mentioned packages are:
Python (>= 2.7 or >= 3.3)
NumPy (>= 1.8.2)
SciPy (>= 0.13.3)
For running the examples Matplotlib >= 1.1.1 is required.
If you are not planning on contributing to the project, but only using it, it is recommended that you download from https://pypi.python.org/pypi/scikit-learn instead of forking it.
View detailed instructions on how to install here.
After installing and building this way, if you still have issues, you can refer http://scikit-learn.org/stable/faq.html for FAQs.

I am not able to install the bz2 package in Python 3 Can please anyone guide
I followed the below commands
sudo yum install bzip2-devel
after that, I start my python 3.7 terminal and use the below command
import bz2
The error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/sysopt/lib/python3.7/bz2.py", line 19, in <module>
from _bz2 import BZ2Compressor, BZ2Decompressor
ModuleNotFoundError: No module named '_bz2'
Based on the comments and the /usr/local/sysopt path, I assume you've installed Python 3.7 from a source package.
When you did that, the Python configure script checked whether it has the bits to compile the bz2 module, and as you didn't have bzip2-devel installed during that time, the builtin bz2 module didn't get compiled.
You will need to recompile and reinstall Python 3.7 to get it included. At that point, you may also want to pay heed to any other optional modules that inadvertently don't get installed; sqlite3 tends to usually be one that ends up missing!

Anaconda installer says that install failed, but won't show the details.
When I try to reinstall, it says Anaconda is already installed into ~/opt/anaconda3, which it is there
python -> import numpy -> Symbol not found: ___addtf3
Environment:
iMac, macOS Catalina 10.15.2
I did do the conda init bash and it seemed to work when I opened a new terminal tab
which python -> opt/anaconda3/bin/python
echo $DYLD_LIBRARY_PATH -> /opt/subversion/lib:/usr/lib:
Oddly in the errors below it's referencing files in /usr/local/lib/python3.7/site-packages/numpy/... but as I said, when I run Python, it starts off with the correct python in ~/opt/anaconda3/bin version, so I don't think it should be looking at /usr/local/lib at all should it??

ImportError:
IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy c-extensions failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that, then:
1. Check that you expected to use Python3.7 from "/usr/local/opt/python/bin/python3.7",
and that you have no directories in your PATH or PYTHONPATH that can
interfere with the Python and numpy version "1.18.1" you're trying to use.
2. If (1) looks fine, you can open a new issue at
https://github.com/numpy/numpy/issues. Please include details on:
- how you installed Python
- how you installed numpy
- your operating system
- whether or not you have multiple versions of Python installed
- if you built from source, your compiler versions and ideally a build log
- If you're working with a numpy git repository, try `git clean -xdf`
(removes all files not under version control) and rebuild numpy.
Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.

I have apache ampps which comes with version 3.6.1 of python.
I was given various directions for installing pip.
None seemed to work.
For example,
link https://packaging.python.org/tutorials/installing-packages/
says that I can run:
python -m pip install -U pip setuptools
Get a whole bunch of errors. It might amount to: no module named queue.
Similar errors happen when I download the file they mentioned (get-pip.py) and run it from python.
Now, when I look at directions for installing queue, some point me to use pip. But when I try to install pip, it is complaining that queue is not there....
Hmmm...?
Now what?

From the format i see here.
Firstly, pip is an installer basically what you've confused yourself with is that pip = queue which is not the case. Pip is just a packager that helps you install packages. Queue is a different module
For your case here Queue is a part of multiprocessing module so you just put this at the top of your code:
from multiprocessing import Queue
and you do not need to add import pip into your code
hope that explained things better for you :)
This line:
python -m pip install -U pip setuptools
means use pip to upgrade the installations of pip and setuptools. Only works if you already have pip - which you probably do. It is a useful step to make sure your install environment is up to date, though.
pip does in places use queue. Note it's been renamed between python2 and python3 - if you have py3, which you claim, you have queue (it was Queue in py2). So I wonder if there's a version mismatch in something.
Windows installs always create problems. You might be safer installing and experimenting with a virtualenv so your experiments don't mess up the python install from the package you mention - ampps. There are plenty of notes on that elsewhere on stackoverflow... e.g. Python and Virtualenv on Windows
pip is already included in 3.6.1, but it is in subfolder Scripts.
it is not automatically a part of the path variable.
you have to change directory and run pip or you can change environment variable so that the location of pip becomes part of the path search.
I'm using Ubuntu 14.04. While I have to retain my "main" python install as 2.7.6, I need to install 2.7.9 to be able to use ssl.SSLContext, to get Flask to deal with HTTPS requests.
However, if I just do:
sudo make install
or
sudo make altinstall
in the Python-2.7.9 directory, I ultimately get:
make: *** [libinstall] Error 1
EDIT: this appears at the end of sudo make install:
...
Compiling /usr/local/lib/python2.7/xml/sax/saxutils.py ...
Compiling /usr/local/lib/python2.7/xml/sax/xmlreader.py ...
Compiling /usr/local/lib/python2.7/xmllib.py ...
Compiling /usr/local/lib/python2.7/xmlrpclib.py ...
Compiling /usr/local/lib/python2.7/zipfile.py ...
make: *** [libinstall] Error 1
So I installed it to a custom directory by modifying the call to ./config, which did not yield the libinstall error.
However, when I try to import Tkinter into Python 2.7.9 (running from the custom directory) I obtain:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/repos/Python279/lib/python2.7/lib-tk/Tkinter.py", line 39, in <module>
import _tkinter # If this fails your Python may not be configured for Tk
ImportError: No module named _tkinter
If I just go ahead and install the vanilla way (i.e., to a non-custom directory) and simply ignore the libinstall error I get, upon importing Tkinter:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/lib-tk/Tkinter.py", line 39, in <module>
import _tkinter # If this fails your Python may not be configured for Tk
ImportError: /usr/lib/python2.7/lib-dynload/_tkinter.so: undefined symbol: PyFPE_jbuf
Does anyone have any idea what is going on?
Following furas' suggestion, installing via the
Python 2.7 PPA maintained be Felix Krull worked spectacularly. Thanks Furas!
EDIT Some notes:
Because this PPA installs python2.7 (specifically v. 2.7.11, as of 1/29/2016), this obviated the need for a custom python install location
While the PPA website mentions that this doesn't include python-tk, provided you have installed it, python plays with it just fine (solving my problem)
First of all source code from a program must be configured, compiled, then installed. You can do this by:
./configure # Or ./config depending on the file name
make
make install
Second of all when you tried to import the module _tkinter you wanted to import the .py file which was called Tkinter.py
Try to use:
import Tkinter
I'm using cairo plot to draw charts with python. I followed the instruction as stated on the website to install Cairplot, http://linil.wordpress.com/2008/09/16/cairoplot-11/ :
sudo apt-get install bzr
bzr branch lp:cairoplot/1.1
The installation completes successfully.
I then try to import the modules in python:
>>> import CairoPlot Traceback (most recent call last): File "<stdin>",
line 1, in <module> ImportError: No
module named CairoPlot
>>> import cairo
>>>
Importing cairo is fine, but I can't figure out why I am not able to import CairoPlot.
bzr branch lp:cairoplot/1.1 creates a directory called 1.1 in your current working directory. Inside you'll find CairoPlot.py. Move CairoPlot.py into a directory which is listed in your PYTHONPATH, or edit your PYTHONPATH to include (the unfortunately named) 1.1.
Is the directory where CairoPlot is installed in your $PYTHONPATH? Do you need to run any setup scripts, like setuptools?
The repository appears to include a setup.py file, so you likely need to run setuptools to fully install the module.
