Today I suddenly discovered that Jupyter can actually be integrated into PyCharm!

Then, I excitedly went to implement the Jupyter + PyCharm + Anaconda environment deployment…

However… things weren’t as simple as I imagined..

After successfully installing the environment, I happily (and confidently) clicked Run Cell. Here’s the error:

Next, I went to the error file: D:\Program Files\anaconda\envs\torchPro\lib\subprocess.py

                                         # no special security

I genuinely searched online with this code for quite a few rounds, but still couldn’t find where the problem was. o(╥﹏╥)o

However, when I switched back to the PyCharm running interface, I found

I had selected the one above before, and didn’t really understand what was going on, but after selecting Python 3, it was resolved.。
