so I had Python 3.7.0 and my Spyder IDE was working fine.
However, because there was no version of tensorflow for that version of python I decided to downgrade my python to version 3.5.0.
Now realising that was a trade-off, I'm assuming there's a correlation there because my Spyder IDE no longer launches, neither does my Anaconda Navigator.
I have already done a Spyder --reset command by the way, no luck.
How can I fix this issue while maintaining to use tensorflow?

I had the possibility to install Python interpreters in PyCharm.
I installed 3.8 Anaconda and others, using them with virtual environments on my projects as we can see here:
For some reason i can not see and change/add new interpreters anymore:
I already deinstalled PyCharm 2021.2 and installed PyCharm 2021.3, but still the same issue. Whats going wrong?
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.
I had OpenCV working fine with PyCharm CE and Python 3.8. Then I upgraded the Mac OS to Big Sur and it stopped working. I reinstalled OpenCV as follows with no effect:
pip3 install opencv-python
pip3 install opencv-contrib-python
I found that the solution was to downgrade the opencv version. In Pycharm, the process is as follows:
In Preferences, go to Python interpreter. You will see the current versions of opencv-contrib-python and opencv-python which may be the same as the latest version.
That is the problem.
Double click on the current version of opencv-contrib-python to open this screen:
Check the specify version checkbox and find version 4.1.2.30. Then click Install Package and wait a few seconds to get a message that package was successfully installed. Press OK and you should see opencv-conbtrib-python downgraded to the appropriate version.
After step 3, opencv-python may have also downgraded to the appropriate version 4.2.0.34. If it hasn't, follow the same process to downgrade opencv-python to 4.2.0.34. At the end, your python interpreter screen should look like this:
That should do it. Test it to make sure it works.
As the title suggests, I have installed Miniconda using for Python 3.7. I see that I have ipykernel but my jupyter-kernelspec is still only python2.
Is there a simple way to just override this? Also, why might this have happened even though I installed the python3 version of miniconda?
Edit: conda info also shows that python is version 3.7
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
