如何在anaconda中设置环境默认的python？

Question

It makes me crazy, In anaconda I create the environment with the defualt iterpreter python3.4 Next I install pytorch 0.4.1

conda install pytorch=0.4.1 cuda80 -c pytorch

After this I found that the pytorch was installed in python3.6!

And the environment defualt interpreter is chaged from python3.4 to python3.6.

I am very confused what happend ? How shoud I fix it back? change defualt python back to python3.4? Hope some one could help me.

The commands I typed in are as follows:

conda create -n pointgen python=3.4 ipykernel
source activate pointgen
conda install pytorch=0.4.1 cuda80 -c pytorch

Thats all. What Novak said is right, there is remaining question is how could I manually change the python version from 3.6 back to 3.4, is there any config file I can deal with?

Answer 1

As you can see here there is no version of pytorch for python3.4... The default version of pytorch is for python3.6 and that is the version you installed installed. In the process anaconda prompts you that it will have to upgrade/downgrade some package versions and there is probably the the line in which it says it will upgrade python to 3.6
