Many thanks. I have just tried to install the jupyter/ispad interface following the instructions at
https://bitbucket.org/kfp/ispad (I had to install libzmp-dev to get it all to work). Now I can start jupyter, and an iSPAD session, but even after the kernel starts and claims to be connected, I can't get my commands to produce output. If I enter, say "2+2" in a cell, and either press Shift-Enter, or choose "Cell/Run" from the menu, no output is produced. What happens is that the prompt to the left of the cell: "In [ ]:" gets an asterisk: "In [*]:". And the prompt doesn't contain a command number. So something, somewhere, is wrong. And in fact, back in the console, there's this: >> System error: Don't know how to REQUIRE SB-BSD-SOCKETS. See also: The SBCL Manual, Variable SB-EXT:*MODULE-PROVIDER-FUNCTIONS* The SBCL Manual, Function REQUIRE ; ; compilation unit aborted ; caught 1 fatal ERROR condition >> System error: READ error during COMPILE-FILE: Package UUID does not exist. Line: 663, Column: 50, File-Position: 25127 Stream: #<SB-SYS:FD-STREAM for "file /home/amca/ispad/ispad.lisp" {1005DDC3D3}> >> System error: The function CL-JUPYTER:KERNEL-START is undefined. Um... what do I do now? Do I need to use quicklisp to install some other files?
