Conda Not Installing Latest Version

I'm installing cvxpy from cvxgrp. Looking a the link it clearly shows version 1.01 for win-64.
However when I go to run the install
conda install -c cvxgrp cvxpy
it downloads and installs "cvxpy-0.4.10". Updating "all" does not seem to help.
I checked conda info and it shows "platform : win-64".
conda info
Is there a conflict? How can I get the latest version?

If you look at the list of files for version 1.01, you'll see that the win-64 build is only for Python 2.7. The installation instructions seem to suggest that you should use pip to install on Windows if you're using Python 3.

Install hazm on anaconda 3

i want to install hazm on anaconda3 .I use this command to install this package with downloaded package :
conda install hazm-0.4.tar.gz
or this command in pycharm :
conda install hazm
in both manner it gives me this error:
Solving environment: failed
PackagesNotFoundError: The following packages are not available from
current channels:
hazm
Current channels:
https://repo.continuum.io/pkgs/main/linux-64
https://repo.continuum.io/pkgs/main/noarch
https://repo.continuum.io/pkgs/free/linux-64
https://repo.continuum.io/pkgs/free/noarch
https://repo.continuum.io/pkgs/r/linux-64
https://repo.continuum.io/pkgs/r/noarch
https://repo.continuum.io/pkgs/pro/linux-64
https://repo.continuum.io/pkgs/pro/noarch
what is the problem ?

The instruction on the hazm documentation page is to install the package using pip:
pip install hazm
pip can be used to install non-conda packages in a conda environment, if there isn't a conda package available.
Reading this question and its answers it sounds as if the latest version of hazm may not install under Windows because of a dependency issue. If you're on Windows you need to specify the 0.4 version, either with hazm==0.4 or simply by pointing to the archive you downloaded. I was able to install hazm 0.4 from the gz archive on Anaconda under Windows without errors as follows:
conda create -n testhazm python=3.4 nltk=3.0.0
activate testhazm
pip install hazm-0.4.tar.gz
(If I allowed conda to use the latest version of nltk, the installation went OK but I got an error when I actually started Python and tried to import hazm. You may be able to get it working with a more recent version of nltk and/or Python by experimenting.)
Background:
When you do conda install hazm the error message The following packages are not available from current channels: hazm means exactly what it says: the channels specified in your current conda configuration do not contain this package.
Often, packages that are not available on the default conda channels can be found on conda-forge, but I checked this with conda search hazm -c conda-forge and it looks like it's not there either.
To use the command conda install hazm-0.4.tar.gz, the downloaded file would need to be a conda package, not just a Python module.

how to get opencv_contrib module in anaconda

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

Can't install wordcloud in python (Anaconda)

I am trying to install wordcloud in my python program. I am doing the following steps. Please tell me where i am doing wrong-
I downloaded the wordcloud package from here https://github.com/amueller/word_cloud
Copy and paste it in the Anaconda3 folder.
Open Anaconda command prompt and give the following command "pip install wordcloud".
The following error is showing -
Please let me know what to do.

You can simply use conda package manager to install wordcloud, just run:
conda install -c https://conda.anaconda.org/conda-forge wordcloud

There is a new version available now but this one worked for me
With Anaconda python 3.6
download from this link.
wordcloud 1.3.2‑cp36‑cp36m‑win_amd64.whl
Then don't extract the file, copy and paste the dir in cmd.
Use this command pip install wordcloud-1.3.2-cp36-cp36m-win_amd64.whl

Open JupyterLab from Anaconda dashboard, in terminal 1, run:
conda install -c conda-forge wordcloud
Source: link

It is trying to build Word Cloud using Visual Studio. If you don't have it you can get a subset called "Microsoft Build Tools 2015" here: https://www.microsoft.com/en-us/download/details.aspx?id=48159
Even having a full version of Visual Studio 2015 and my path set up properly I still had trouble installing using pip. I also had no luck with the conda installer. The following worked for me:
Go to http://www.lfd.uci.edu/~gohlke/pythonlibs/#wordcloud and download the wheel for the version of Word Cloud you need.
From the command prompt install using pip. For example, pip install wordcloud-1.2.1-cp27-cp27m-win_amd64.whl

Using Anaconda Python 3.6 version For Windows you can do it as:
Installation of wordcloud package
download wordcloud‑1.3.2‑cp36‑cp36m‑win_amd64.whl from
http://www.lfd.uci.edu/~gohlke/pythonlibs/#wordcloud
Copy the file to your current working directory
Open command prompt
python -m pip install wordcloud-1.3.2-cp36-cp36m-win_amd64.whl

I have python 3.6.3 installed on my windows system. I installed wordcloud package in python but faced the "wordcloud No Module Found" error on Anaconda Jupyter Notebook.
I tried most of the solutions posted here but nothing worked for me.
Finally I installed wordcloud package in the Scripts directory under Anacond3 directory in the command prompt using:
pip install wordcloud
This worked and I am able to import wordcloud on Jupyter now.

I've got the similar error but related to certification, if the error is:
Caused by SSLError(SSLError("bad handshake: Error([(\'SSL routines\', \'ssl3_get_server_certificate\', \'certificate verify
failed\')])",),))',),)
This other SO question helped me. It basically said to do:
conda config --set ssl_verify false

After a long try:
1) Download the latest version of WordCloud from this link.
2) Copy it into the Script directory under Anaconda3.
3) Open the command prompt and do pip install wordcloud. (If a win[5] authorization error occurs, try doing pip from the admin command prompt or sudo pip install wordcloud.)

You should have a virtual environment for each project or group of projects that use a particular set of packages. I use Anaconda. Jupyter should be installed in each of your virtual environments. Let's assume you've already created the environment foo. Then:
conda activate foo
conda install jupyter
conda install -c conda-forge wordcloud
Now when you do the import it should work. My import:
from wordcloud import WordCloud, STOPWORDS

How to install Gensim version 0.11.1 on Windows 10 Machine?

I have anaconda and Pip installed. I tried doing
conda install -c anaconda gensim-0.11.1
but it couldn't find the package and the following msg was thrown on the PowerShell.
Using Anaconda Cloud api site https://api.anaconda.org
Fetching package metadata: ......
Solving package specifications: .
Error: Package missing in current win-64 channels:
- gensim-0.11.1
You can search for this package on anaconda.org with
anaconda search -t conda gensim-0.11.1
Any help would be appreciated. Thanks!
--Conda works well with the machine but even help with Pip would be appreciated.

Any reason you need the 0.11.1 version? That version hasn't been specifically built as a conda package apparently.
At the moment, conda install gensim will easily give you version 0.12.4.
If you really need version 0.11.1, first
conda install scipy pip
then
pip install gensim==0.11.1
