I have installed conda on linux ubuntu 16. When I install or update a package named sentencepiece it install the version 0.1.85 (which I guess is from 2 months ago according to anaconda website). However the latest version is 0.1.91.
I can't install the latest version so that I can use it in python because I guess it refers to the conda packages. I tried to follow an instruction in the package home on github and installed the latest version using a package manager named vcpkg. However, I don't think it has any effect on python or conda, as a sample program didn't compile and the conda still list it as 0.1.85
please guide me what can I do
Use pip instead of conda
First step - conda activate <your_env>
Next step - pip install sentencepiece
Then last step - check the version using pip freeze | grep "sentence*"
Output should be sentencepiece==0.1.91

I am trying to install the v2.7.0 of the eccodes package.
But this is not working:
conda install -c conda-forge eccodes=2.7.0
I can see the versions here: https://anaconda.org/conda-forge/eccodes/files?version=2.7.0&page=2
What I am doing wrong with the syntax?
The latest version is 2.13, which I don't want.
If you look through all of the package versions on the first page, you will notice that their label is 'main'. However, the version you want to install has the label 'cf201901'.
You should therefore change your install command to:
conda install -c conda-forge/label/cf201901 eccodes=2.7.0
By including the label in the channel it will be able to find the correct older version.
Alternatively, you can copy the link of the old package directly from the website you were browsing and just run:
conda install https://anaconda.org/conda-forge/eccodes/2.7.0/download/osx-64/eccodes-2.7.0-0.tar.bz2
If you want to install version 2.7.0 for osx
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.
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
I want to install Tensorflow 1.o for python on windows.
This is information for my system.
D:\>python --version
Python 3.5.2 :: Anaconda 4.2.0 (32-bit)
D:\>pip3 --version
pip 9.0.1 from d:\web\anaconda\lib\site-packages (python 3.5)'
But, when I execute below command,
D:\>pip3 install tensorflow
Collecting tensorflow
Could not find a version that satisfies the requirement tensorflow (from versions: )
No matching distribution found for tensorflow
I don't understand what the problem is...
And I tried another way...
This is case when I use Conda
(tensorflow) D:\>pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-1.0.0-cp35-cp35m-win_x86_64.whl
tensorflow-1.0.0-cp35-cp35m-win_x86_64.whl is not a supported wheel on this platform.
What is the problem?
I was in same problem.
Below command solved my problem
pip3 install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-1.0.0-py3-none-any.whl
to find the list of all the urls based on the python version and CPU or GPU only refer to:
https://www.tensorflow.org/install/pip
Tensorflow requires a 64-bit version of Python.
Additionally, it only supports Python 3.5.x through Python 3.8.x.
If you're using a 32-bit version of Python or a version that's too old or new, then you'll get that error message.
To fix it, you can install the 64-bit version of Python 3.8.6 via Python's website.
Tensorflow on windows needs python 3.5. You can follow following steps to activate python 3.5 in anaconda:
See which version of python you have: conda search python
If you already have python 3.5 then go to step 3
otherwise use conda create -n py35 python=3.5 anaconda to create python 3.5
Activate python 3.5 using activate py35
Now install tensorflow using conda install tensorflow
If step4 is not working i.e, something like "tensorflow: no package found " then follow this tutorial to forge conda-forge channel and then try installing tensorflow using step4. It worked for me.
Try this
Installing with Anaconda
conda create --name tensorflow python=3.5
activate tensorflow
conda install jupyter
conda install scipy
pip install tensorflow
or
pip install tensorflow-gpu
It is important to add python=3.5 at the end of the first line, because it will install Python 3.5.
I was getting the same error
Get Python 3.5
Upgrade pip version to 9
Install tensorflow
It worked for me
I did it with:
python3 -m pip install --upgrade tensorflow
From your python version output, looks like that you are using Anaconda python, in that case, there is a simple way to install tensorflow.
conda install -c conda-forge tensorflow
This command will take care of all dependencies like upgrade/downgrade etc.
upgrading pip worked for me
python -m pip install --upgrade pip
i had python 3.8.5 ..but it will not work with tenserflow..
so i installed python 3.7.9 and it worked.
The solution for me was sooo dumb!!
I was using Python 3.8 in my environment. I made a new environment using Python 3.7, and the install worked fine.
source
The TensorFlow package couldn't be found by the latest version of the "pip".
To be honest, I really don't know why this is...
but, the quick fix that worked out for me was:
[In case you are using a virtual environment]
downgrade the virtual environment to python-3.8.x and pip-20.2.x
In case of anaconda, try:
conda install python=3.8
This should install the latest version of python-3.8 and pip-20.2.x for you.
And then, try
pip install tensorflow
Again, this worked fine for me, not sure if it'll work the same for you.
The Reason is that TensorFlow is only available upto python versions <= 3.6. You can't download tensorflow for python versions > 3.6 as there is no tensorflow.
If you don't want to downgrade your entire python version for a single package, do this:
create a new virtual environment for that project (using anaconda)
conda create -n <env_name> python=3.6.8
activate the created environment using conda activate <env_name>
Now install pip install tensorflow
note: If tensorflow dosen't install : try install keras module first and then try installing tensorflow
I have the anaconda distribution of python installed on my machine. Before installing anaconda, i had pip installed. Right now, my system uses the previous version of pip rather than the anaconda version. In particular
arjuns-mbp:~ Arjun$ which pip
/usr/local/bin/pip
arjuns-mbp:~ Arjun$ which easy_install
/Users/Arjun/anaconda/bin/easy_install
arjuns-mbp:~ Arjun$ which python
/Users/Arjun/anaconda/bin/python
The result is that if i call a pip install, it won't add it to my anaconda version of python. So far i haven't had an issue simply using easy_install to add packages to anaconda, but it would be nice to know what causes this discrepancy and how to fix it
EDIT
i tried using conda install pip, it doesn't work. When I do
conda list
pip showed up before and after a conda install
You probably need to conda install pip.
pip should already come with Anaconda automatically. How did you install Anaconda? No matter, though, you can just conda install pip to make sure you have a version of pip that is tied to the Anaconda distribution.
From there you can create environments as much as you like to install whatever new trial-run software tools using conda create -n env_name python pip
