My commands are like this:
vector([x1,y1,z1])
r1 = _
And I get this message:
Error in lines 1-1
Traceback (most recent call last):
File "/cocalc/lib/python2.7/site-packages/smc_sagews/sage_server.py", line 995, in execute
exec compile(block+'\n', '', 'single') in namespace, locals
File "", line 1, in <module>
NameError: name '_' is not defined
However, copying and pasting commands into a new worksheet make that feature work again. Why?
I have links to illustrate it, but my karma is insufficient to post them here.
