I'm running a fresh sandbox using the link from the "Introduction to q" page. The Jupyter notebook fails on the first setp:
Cell In[15], line 1
system "cd ",.trn.nbdir:$["/"=first v;"";getenv[`HOME],"/"],v:first system "dirname '",getenv[`JPY_SESSION_NAME],"'"
^
SyntaxError: invalid syntax
That should mean that the q script is interpreted as a Python 3 script, and the problem is in the kernel selection. But the only kernel available is Python 3. What am I doing wrong?
