Upgrade to python 3.8 using conda
Solution 1
You can update your python version to 3.8 in conda using the command
conda install -c anaconda python=3.8
as per https://anaconda.org/anaconda/python. Though not all packages support 3.8 yet, running
conda update --all
may resolve some dependency failures. You can also create a new environment called py38 using this command
conda create -n py38 python=3.8
Edit - note that the conda install
option will potentially take a while to solve the environment, and if you try to abort this midway through you will lose your Python installation (usually this means it will resort to non-conda pre-installed system Python installation).
Solution 2
Open Anaconda Prompt (base):
- Update conda:
conda update -n base -c defaults conda
- Create new environment with Python 3.8:
conda create -n python38 python=3.8
- Activate your new Python 3.8 environment:
conda activate python38
- Start Python 3.8:
python
Solution 3
Now that the new anaconda individual edition 2020 distribution is out, the procedure that follows is working:
Update conda in your base env:
conda update conda
Create a new environment for Python 3.8, specifying anaconda for the full distribution specification, not just the minimal environment:
conda create -n py38 python=3.8 anaconda
Activate the new environment:
conda activate py38
python --version
Python 3.8.1
Number of packages installed: 303
Or you can do:
conda create -n py38 anaconda=2020.02 python=3.8
--> UPDATE: Finally, Anaconda3-2020.07 is out with core Python 3.8.3
You can download Anaconda with Python 3.8 from https://www.anaconda.com/products/individual
Solution 4
Update for 2020/07
Finally, Anaconda3-2020.07 is out and its core is Python 3.8!
You can now download Anaconda packed with Python 3.8 goodness at:

Python 3.8.0 is out, but I haven't been able to find any post on how to update to python 3.8 using conda - maybe they will wait for the official release? Any suggestions?

conda update conda; conda create -n py38 -c anaconda python=3.8

egnha over 4 yearsYou can drop the channel specification, since Python 3.8 is now on the default channel. Thus
conda create -n py38 python=3.8
will create a minimal environment with Python 3.8. -
Amelio Vazquez-Reina over 4 yearsIf I'm not in an environment, does
conda install -c anaconda python=3.8
update the base installation? -
mcguip over 4 yearsYes this should be the case.
-
loveR over 4 yearsI wonder why Anaconda for python 3.8 version is still not out?
-
WSLUser over 4 yearsI can confirm it updates the base as I just did it. Conda-forge does offer a newer update of 3.8 for awareness.

BrtH over 4 years"note that the conda install option will potentially take a while to solve the environment". In my case the conda message said it would take 'several minutes', this ended up being about 5 hours...

Gilberto Albino over 4 yearsThis solution got the job done and worked like a charm in Anaconda Prompt, but it didn't got available outside it. Any clue on how to make the activated python available system wide?

Netverse over 4 yearsYou will need to switch to your newly created python environment using command conda activate

ijoseph about 4 years@nba2020 that's absurdly long. It's probably NP-hard to calculate dependencies or something. At this point it'd be much faster to create a new conda env and install what you need.
-
variable about 4 yearsThe install command which specified you have specified - does it install python 3.8 along side existing python (I have 3.6 existing) or does it upgrade the existing to 3.8?

Rishabh Deep Singh about 4 yearsIt is only showing like 17 items on the list. why not the full list?

AbuTaareq about 4 yearsWhen I active using windows command shell it failed. Later, I change to directory where my environment installed, then typed just "activate" solved my issue. I validate by typing python gives me latest 3.8.2 version. I search for the environment directory by "conda info --envs" in the command line.

Sarthak Kumar about 4 yearsThis solution is correct but what should be done to upgrading python in base env?
-
FabPop about 4 years@nba2020: I can confirm, it takes forever to compute a long list of conflicts and it stops there. So, there does not seem to be a way to upgrade python from 3.7 to 3.8
