I am using Anaconda python (2.7) on my Windows 7 machine. I want to install specutils which is a associated package for Astropy.
conda, as I understand, can installs binaries using conda install <package> command. My question is
where can I find the binary version of the specutils in the above cited repository.
How do I install specutils using conda?
You can install specutils with conda:
$ conda install -c astropy specutils
This installs specutils from the astropy anaconda channel (I'm almost certain that you can find the binaries there). If you want to install the development version you can also use:
$ pip install git+https://github.com/astropy/specutils.git#master
There are no stable releases of specutils yet, but you can install it by doing:
git clone https://github.com/astropy/specutils.git
cd specutils
python setup.py install
The specutils docs can be found here, and please report any issues here

I'm using Winpython to do a project but i'm struggling to install a package with pip. This package is easily installed using "conda install" in my Anaconda. I would like to know if there is some way to use the conda package manager in Winpython (i.e install package using conda install in Winpython)
No. Depending of what you miss:
download big binary packages from https://www.lfd.uci.edu/~gohlke/pythonlibs/ in a local directory "d:\toto"
"pip install --pre --no-index --trusted-host=None --find-links=d:\toto your_package"
or
"pip install d:\toto\your_package_wheel_exact_name"
I have Python 3.8.5
How can I install the package vtkplotter with this Python version?
Thanks a lot!
It appears that vtkplotter has migrated to vedo (Link to GitHub repo with installation instructions). Maybe you are better off using vedo for newer Python versions.
Use pip or conda or whatever to install your package.
If you find that a certain version of Python is not compatible with a specific version of a library, you can make a virtualenvironment with a specific python version that is compatible with the package, activate the virtual environment, and then install your package.
you can install it by conda
To install this package with conda run one of the following:
conda install -c conda-forge vtkplotter
conda install -c conda-forge/label/cf202003 vtkplotter
Whenever I run:
pip install fastai
I get the error
"Command "python setup.py egg_info" failed with error code 1 in C:\Users\seja9890\AppData\Local\Temp\pip-install-_cw7ve61\torch\".
Can someone please guide me where I might be going wrong?
Ps.: I have tried updating setuptools and it doesn't help in my case.
Fastai doesn't work with Python 2 so make sure you installed pip3 (sudo apt install python3-pip on Ubuntu).
Make sure Python3 is at least 3.6 this may change since Fastai may need 3.7. soon.
and then:
pip3 install git+https://github.com/fastai/fastai.git
or use pip3 install fastai, or in some cases you may need:
pip3 install --no-deps fastai
Note: At the moment I am writing this: PyTorch v1 and Python 3.6 are the minimal version requirements.
For official website, you should install it with conda.
anaconda
fast.ai
To install
# Prerequisites
Anaconda, manages Python environment and dependencies
# Normal installation
Download project: git clone https://github.com/fastai/fastai.git
Move into root folder: cd fastai
Set up Python environment: conda env update
Activate Python environment: conda activate fastai
If this fails, use instead: source activate fastai
# Install as pip package (not recommend)
You can also install this library in the local environment using pip
pip install fastai
However this is not currently the recommended approach, since the library is being updated much more frequently than the pip release, fewer people are using and testing the pip version, and pip needs to compile many libraries from scratch (which can be slow).
An alternative is to use the latest Github version with pip
pip install git+https://github.com/fastai/fastai.git
I downloaded the latest stable Anaconda install off the Continuum website which turned out to be Anaconda 4.3.1 (64-bit) and comes with Python 3.6.0. I am in a Windows 10 environment.
However pip3 is missing and I cannot install any Python 3.x packages via pip3.
What am I doing wrong?
If you do not have another environment installed python 3+ will default to just pip I believe since pip3 is just an alias for pip.
pip install --upgrade pip
or You can do it with the associated Python binary too; if it executable as python3, then use that:
python3 -m pip install --upgrade pip
after that check:
pip --version
otherwise just try pip-3.6
for tensorflow on conda:
pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-1.0.1-cp35-cp35m-win_amd64.whl
for python 3.6 due to conda providing the 3.5 one: from
pip install https://testpypi.python.org/packages/db/d2/876b5eedda1f81d5b5734277a155fa0894d394a7f55efa9946a818ad1190/tensorflow-0.12.1-cp36-cp36m-win_amd64.whl
Since this wheel had a version that is undesirable we could instead install
the wheel directly from gohlke's windows binaries repository :
download the wheel for python 3.6 from here and then install the wheel:
cd to the directory containing .whl file:
pip install some-package.whl
easy_install pip
I used it, for the problem of pip installation in miniconda.
sometimes the pip is not properly installed but it claims yes
Solution:- (Note:- This will surely work for all!!)
Step 1:- conda search python
Step 2:- conda install python=3.5.2
Step 3:- pip install tensorflow
Step 4:- import tensorflow as tf
I have Windows10, 64bit, Anaconda4.3 with Python 3.6.
Karthik' soluton worked for me. Before that I tried everything including "conda create -n tensorflow python=3.5", but it did not work (although "python --version" gave 3.5.3).
you should be able to install tensorflow using
$ conda install -c conda-forge tensorflow
Can anyone tell me commands to get contrib module for anaconda
I need that module for
matches = flann.knnMatch(des1,des2,k=2)
to run correctly
error thrown is
cv2.error: ......\modules\python\src2\cv2.cpp:163: error: (-215) The data should normally be NULL! in function NumpyAllocator::allocate
Also I am using Anaconda openCV version 3, and strictly dont want to switch to lower versions
P.S. as suggested at many places to edit file cv2.cpp option is not available with anaconda.
I would recommend installing pip in your anaconda environment then just doing: pip install opencv-contrib-python. This comes will opencv and opencv-contrib.
Anaconda supports pip install to install package into conda environment. You can download OpenCV 3.2.0 with opencv_contrib from this well known Unofficial Windows Binaries for Python Extension Packages website. See the filename below for the right version. Then type the command in Anaconda Prompt window to install the package:
For Python 3.5 and 64-bit Windows:
pip install opencv_python‑3.2.0+contrib‑cp35‑cp35m‑win_amd64.whl
For Python 3.6 and 64-bit Windows:
pip install opencv_python‑3.2.0+contrib‑cp36‑cp36m‑win_amd64.whl
Most of the OpenCV 3.2.0 packages in Anaconda repository didn't specific if they come with opencv_contrib. The pip install approach is easier and proven, see one of the SO post. The only drawback is that conda list will not show pip installed package there but actually it's.
However, if you want to have trial on conda install, below is the command for installing OpenCV 3.2.0 for Python 3.5 or 3.6 but likely without opencv_contrib.
conda install -c conda-forge opencv=3.2.0
Hope this help.
You can try this: https://anaconda.org/michael_wild/opencv-contrib
To install this package with conda run:
conda install -c michael_wild opencv-contrib
These anaconda packages include the contrib modules with base OpenCV3. Though the file list says it's currently for Windows only!
The question is old but I thought to update the answer with the latest information. My Anaconda version is 2019.10 and build channel is py_37_0 . I used pip install opencv-python==3.4.2.17 and pip install opencv-contrib-python==3.4.2.17. Now they are also visible as installed packages in Anaconda navigator and I am able to use patented methods like SIFT etc.
Method 1: in Anaconda Prompt write this, will install opencv-contrib v4.6
pip install opencv-contrib-python
Method 2: Install previous version of opencv-contrib v3.3.1
According to https://anaconda.org/michael_wild/opencv-contrib it says it support win64bit only and python 3.6.x.
So, first you need to create new enviroment support python 3.6
conda create --opencv_contrib36 python=3.6.13
then, install the packages
conda install -c michael_wild opencv-contrib
There is repo in conda-forge which includes opencv-contrib: https://github.com/conda-forge/opencv-feedstock
To use it:
conda install --channel=conda-forge libopencv opencv py-opencv
if you run into Numpy error, try pinning more recent version (of Numpy).
This worked for me in Windows 10 on Anaconda 5.3 with python 3.6
conda install -c conda-forge opencv
