Hello I need to create an anaconda environment with python version = 2.7.9. The issue is that there are no ways that I can install that python version using conda. The channels that I have doesnt provide me that version, is there a way in which I can install a specific version of python using conda giving the fact that my current channels doesnt provide me the required version?
There is an archived version available on the free channel. Try
conda create -n py279 -c free python=2.7.9

I want to upgrade my base environment to Python 3.8. According to the official documentation, I should just run conda install -c anaconda python. This, however, only upgrades Python 3.7, so, in the end:
(base) C:\Users\bob>conda install -c anaconda python
Collecting package metadata (current_repodata.json): done
Solving environment: done
# All requested packages already installed.
(base) C:\Users\bob>python --version
Python 3.7.6
conda update -c anaconda python only updated a number of packages, but not Python itself.
And if I specify a version, like explained here, after two hours analyzing dependencies, the upgrade fails because of conflicts.
I managed to set up a 3.8 environment, but I'd rather upgrade my base environment as it's the one my system path for use outside of Anaconda.
Any suggestion?
It doesn't appear to be possible to update the base version of anaconda to 3.8 yet because of the conflicts you mention. I assume once all the standard packages are updated to support 3.8+ (and updated versions of all dependencies), then the anaconda release will include 3.8.x as the default. This might take a while.
The problem here is version conflicts in the packages that anaconda installs by default. The reason you can install 3.8 in a clean environment is because no other packages are installed in that environment, so no conflicts.
This does now present a solution, although it requires reinstalling everything from scratch...
disclaimer: I don't use windows, so adapt my instructions accordingly to your OS.
Remove your existing anaconda install from the path and delete
anything in your bashrc (or windows equivalent) that points to it.
You can just delete/uninstall anaconda, but it's good to have a backup just incase, so leaving it there and removing links to it is a good option.
Download and install miniconda, and put it in your path as you had before.
Install python 3.8 in the base environment conda install python=3.8
Install all the packages that you need to do whatever you do.
Depending on what you install, at some point you may run into the same conflicts that prevent a standard anaconda install from updating at the moment, but that hasn't happened for me.
The latest stable version of anaconda is version 3.7
Please see here:
https://www.anaconda.com/distribution/
There isn't an option to get python 3.8, this is due to anaconda sometimes running a version behind the release of python.
I had the same issue and found there is a 2020-07 release of Anaconda with Python 3.8 https://www.anaconda.com/products/individual
I'm new to programming and following a course where I must install Tensorflow. The issue is that I'm using Python 3.8 which I understand isn't supported by Tensorflow.
I've downloaded Python 3.6 but I don't know how to switch this as my default version of python.
Would it be best to set up a venv using python 3.6 for my program and install Tensorflow in this venv?
Also, I using Windows and Powershell.
Tensorflow is only supported until python 3.7 as of now.
You can check it here: https://www.tensorflow.org/install/pip
But there is a way to install it on Python3.8, just run the below command that will do your job:
python -m pip install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-1.12.0-py3-none-any.whl
This command work on mac and windows both, I haven't tested on Linux.
You should always use venv because by default every project on your system will use these same directories to store and retrieve site packages (third party libraries). At first glance, this may not seem like a big deal, and it isn’t really, for system packages (packages that are part of the standard Python library), but it does matter for site packages.
Consider the following scenario where you have two projects: ProjectA and ProjectB, both of which have a dependency on the same library, ProjectC. The problem becomes apparent when we start requiring different versions of ProjectC. Maybe ProjectA needs v1.0.0, while ProjectB requires the newer v2.0.0.
You can also take a look at anaconda, it’s the most populasr data sciencie platform and will be easy for you install tensorflow and jupiter notebook in just 2 clicks. Anaconda
Uninstall all your python versions and use the latest anaconda.
$ conda create --name tensorflow python=3.5
This way you create a virtual environment with python 3.5 which is supported by tensorflow.
So now you can install it.
$ activate tensorflow
(tensorflow) $ pip install tensorflow
it would have been nice if you would have the share the error screenshot
though as per i got the case
tensorflow work in both 3.8 and 3.6 just you have to check that you have 64bit version not 32 bit
you can acess both version from thier respective folder no need to install a venv
If you don't want to use Anaconda or virtualenv, then actually multiple Python versions can live side by side. I use Python38 as my default and Python35 for TensorFlow until they release it for Python38. If you wish to use the "non-default" Python, just invoke with the full path of the python.exe (or create a shortcut/batch file for it). Python then will take care of using the correct Python libs for that version.
Worked on Python 3.8.2 (default, Mar 05 2020, 18:58:42) [GCC] on linux
pip3 install --upgrade tf-nightly
Python Versions 3.5 - 3.8 are supported now.
You can verify on this page:

At time of writing, alpha version 3.8.0a4 of python is available. I would like to do some testing in a conda env before it is GA (for both educational purposes and to satisfy some curiosities).
When trying to conda install 3.8 I am getting a PackagesNotFoundError error. Are alpha/beta versions of python simply unavailable through conda channels or is there perhaps an alternate conda channel where this might be found?
I know the latest version can be found on python.org in downloads/release but was really hoping for availability in a conda channel, if possible.
3.8.0a3 can be downloaded using conda-forge, which is a custom channel for conda. You can see the package listed here, with version 3.8.0a3 being labelled as pre-3.8. Unfortunately, it doesn't look like 3.8.0a4 is available yet.
conda install -c conda-forge/label/pre-3.8 python
There is an open issue on conda-forge for adding 3.8.0a4.
I am trying to work with opencv 3.0 on my Mac OS 10.12.6
I am working with Anaconda in a python 3.5 environment, and have tried the following command in terminal:
conda install -c jlaura OpenCV3
from the following: https://anaconda.org/search?q=platform%3Aosx-64%20opencv3
However, this ends up giving the following output/error:
PackageNotFoundError: Packages missing in current channels:
opencv3 -> tbb
We have searched for the packages in the following channels:
(This is followed by a number of links, which stack overflow will not let me post as I don't have enough rep yet)
What is the best way to get opencv 3.0 on conda with a python 3.5 environment?
I need this because I am trying to implement the following: https://github.com/datitran/object_detector_app
Thanks
I essentially had to reinstall python 3.5 using:
conda install python=3.5
and then get the opencv 3.0 version like so:
conda install -c jlaura opencv3
And that did it.
I ran into the exact same problem, trying to use the same repo, however the above did not work for me. Eventually I was able to download openCV 3.0.0 by running
conda install -c memex opencv
If this has for some reason deprecated, you can always search for another option on the anaconda cloud website. Just ctrl-f for 3.0.0 and find a package that includes your platform (osx in my case).
I'm trying to install Tensorflow.
I created a fresh Debian 8 VirtualBox for this purpose. Following the instructions here I downloaded and installed Anaconda with Python 3.
I created a conda environment for Tensorflow and activated it.
When trying to pip install Tensorflow it fails:
(tensorflow)$ pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.8.0-cp34-cp34m-linux_x86_64.whl
The error is
not a supported wheel on this platform
I found a similar thread where a person had this problem with Python 2.7 and VMware, but their solution didn't work for me (and also not for another person who commented that they were using VirtualBox).
I also tried specifying pip3 and pip3.5 rather than just pip.
This appears to be a "known" issue from the following issue. Which paraphrased you should be able to download https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.8.0-cp34-cp34m-linux_x86_64.whl and change the name of the .whl to tensorflow-0.8.0-py3-none-linux_x86_64.whl and install it correctly. There has been a change to the github documentation for Tensorflow to set the python version to 3.4 instead of 3.5. However, it appears this change hasn't made it to Tensorflow.org's documentation
# Python 3.4
$ conda create -n tensorflow python=3.4
