How did my anaconda change to use Python 2.7?
问题 I installed Anaconda for Python 3.7, and I created an environment tf to install lots of library, including iPython. After I logged into iPython terminal, I can see that it is using Python 3.6. I have been using environment for a while. However, today after I use conda install pil to install a library, i can see that a lot of libraries are updated. After the installation, when I logged into iPython again, it shows that "Python 2.7.15" in the same environment tf . How can I switch back to use
