I learned that there are some issues in the latest Anaconda 3 python 3.7 version for object detection and face recognition deep learning problems from various posts. The official Anaconda site is only providing the latest python 3.7 version here. I want to work on a similar deep learning project in Windows 10(64 bit) which requires Anaconda 3 with python 3.6 version.
I found several posts providing solutions on StackOverflow for a Linux environment but I could not find any solution for the Windows 10 operating system. Can anyone share with me how to download the Anaconda 3 python 3.6 version?.
Any help will be highly appreciated.
Recommendation: Learn how to use conda by reading get started with conda. The problem you encounter is a very common case could be solved by conda, as an environment manager.
Solution 1
Use an environment with Python 3.6 installed, and activate this environment each time to work with your project.
# create an environment with python 3.6
conda create -n py36 python=3.6
# activate this environment
conda activate py36
This is also the preferred way to work with different projects. One environment for one project.
Solution 2
The default environment you're using with conda is base. You can override the Python 3.7 within base with Python 3.6
conda install -n base python=3.6

Spyder-terminal does not install with Anaconda Navigator running Python v3.8 or v3.9 or v3.10.
My question is "Is there a way to install the Spyder-Terminal Plugin using Anaconda Navigator running Python 3.8 or 3.9 or 3.10, and use Spyder v5.x " ?
Is there a hack for this to run inside Spyder 5.0.x on Python 3.8, 3.9 or 3.10, WITHOUT creating a new virtual environment?
My Software Versions
Spyder-Terminal Version: spyder-terminal-0.5.0 (spyder-ide/win-64)
Python Version: 3.8 or 3.9
Anaconda v2.0.1
Operating system: Windows 10
What I tried:
I tried installing 'conda install -c spyder-ide spyder-terminal' from Anaconda Command Prompt. I did several trials with MANY errors to learn that Spyder-terminal only works with Spyder v4.2 and NOT Spyder v5.0.3.
Spyder-terminal is (nominally) supposed to work in Python 3.9. So I tried upgrading Anaconda base environment to Python 3.9. However, that BROKE the Anaconda base environment, which required uninstalling and reinstalling the entire Anaconda distribution. (What a hassle. Good thing this was on someone else's computer! 8^))
I finally got it to work in a separate conda virtual environment running Python 3.6. Just to be conservative, I used Python 3.6 instead of Python 3.7. (I later installed Spyder-Terminal in a Python 3.7-based virtual environment and it worked fine.)
The steps that finally worked were to Create a new conda environment with Python 3.6 and install spyder-terminal and spyder-notebook there.
I used the following commands...
conda create -n python36 -c conda-forge python=3.6
conda install spyder-terminal -c conda-forge spyder-ide
conda install spyder-notebook -c conda-forge spyder-ide
The correct version of Spyder (for Python 3.6) was installed along with all of its correct dependencies.
What steps will reproduce the problem?
try installing into an Anaconda distribution with Python 3.8 or Python 3.9 kernels
Wait a long time and get many errors.
Rip out a few locks of hair (preferably someone else's)
**What is the expected output?
Spyder-Terminal plugin installs and is available for use.
What do you see instead?
A bunch of errors. The exact errors were lost when I closed the installation console.
Suggestions
The Spyder-terminal plugin failed repeatedly in Anaconda "base" running v3.8.x or a new environment running v3.9.x. I used a new conda virtual environment, running Python 3.6 runtime kernel and install spyder-terminal there.
The Spyder-terminal installer should do version checks for Python and Spyder FIRST, warn the user, and stop if they are not using Python 3.6 or Python 3.7.
Clearer documentation for Spyder-Terminal plugin installation on the Github.com home page (or built into Spyder Menu "Help" will help the "HELP" system. These docs should state WHICH version(s) of Spyder and Python that Spyder-Terminal v0.5.x requires. A dependency table would also be useful.
In one existing conda environment, the python is 3.8. Is that possible to downgrade the python version for this specific environment from 3.8 to 3.6 or 3.7?
Check this,
Open your terminal and search for available versions using the following command.
conda search python
If the python version you are searching is available then use the command
conda install python=3.8 (0r 3.6 or 3.7 depending to your requirement)
This will change the python version in a specific environment.
Note: This command will overwrite the default python version.
I suggest you open a new conda environment using the following command.
conda create --name py38 python=3.8
//This lines will create a new environment named py38
Now you can work into this environment without interfering with the libraries of the other environment.
Hope this will help you.
We have Anaconda installed on my cloudera cluster via parcels. We have python 2.7.13 available with the version of Anaconda. We wanted to have another version of python (3.6) across all nodes.
My challenge here is, when I followed the Conda documentation to create a new environment and install python 3.6 on that using "conda create -n py36 python=3.6 anaconda". For few nodes, I am getting python3.6.6 installed for few nodes, and python3.6.7 for few nodes and 3.6.1 for few.
I would like to know if there is a way to choose the version of python while installing 3.6 on a separate environment. Or am I doing something wrong? Please help me.
Thanks

You can specify the patch as well
conda create -n py36 python=3.6.7 anaconda
I have a new laptop (dell xps 9570) on which I have installed fedora 29 which I will use for coding/data science.
Fedora 29 uses Python 3.7 but Tensorflow is not compatible with that version, so how can I use Python 3.6 without overriding system's default?
I have heard recently about virtual environment for Python but I don't know much about it, so I wonder is it possible to install Python 3.6 on a virtual environment?
Thank you
You can't install Python itself with pip; just Python packages.
You could use something like Conda. That provides a more separate (virtual) environment, including the Python executable. Conda also provides TensorFlow (up to version 1.12.0), which should make for a relatively easy installation:
conda create -n tensorflowenv python=3.6 tensorflow
Conda may take a while to solve the environment; just let it run, and it will likely install Python 3.6 in the Conda environment (whilst keeping your system Python 3.7), where you can then use TensorFlow.
I have the Anaconda distribution installed for Mac. I have Mac OSX 10.8 (Mountain lion). The problem I don't often use Anaconda is because the default Python which it uses is 2.7 while I work on 3.3 or atleast prefer to work on that.
I really like the Spyder IDE of Anaconda. Is there a way I can get the default environment on Anaconda changed to 3.3 instead of 2.7 so that Spyder and iPython all use 3.3 default?
I see the following help from Anaconda site:
$ conda create -n py3k python=3 anaconda
Here python=3 and anaconda are package specifications, and it is the job of the SAT solver inside conda to find a consistent set of packages which satisfies these requirements. As the root environment uses Python 2, we had to specify the major version explicitly.
After adding the binary directory of the newly created environment to the PATH environment variable, which may be done using
$ source activate py3k
My question is I have separately installed Python 3.3 and associated Scientific Python packages like Pandas, numpy, scipy, scikit-learn etc using Homebrew so that it doesn't conflict with my Mac OS default Python 2.7. So now if I run the above Conda commands in Mac Terminal will it interfere with other Python packages I have installed using Homebrew? or will it automatically install/upgrade the python and other packages in the Anaconda library without interfering with either the Homebrew installed Python or Mac OS default Python?
Please advise.
No, the Homebrew and Anaconda Pythons will stay completely independent of one another. Just make sure you don't have PYTHONPATH set, which causes this to not be true.
Also, you should know that Spyder is not available for Python 3 in Anaconda yet, because PySide has not yet been built for Python 3.
I had installed Anaconda with python 2.7, but even after adding python3:
conda create --name Py3 python=3
spyder continued to call python2.7
creating an environment with BOTH spyder and python=3 worked for me:
conda create --name SpyPy3 python=3 spyder
