The only problem I see with this is that we&#39;ve created an external file required to define how to run jupyter which breaks the &quot;everything defined inside the notebook&quot; aim?</p> </div><!-- SC_ON --> &#32; submitted by &#32; <a href="https://www.reddit.com/user/__-----_-----__"> /u/__-----_-----__ </a> <br/> <span><a href="https://www.reddit.com/r/GUIX/comments/q0rvpd/guixjupyters_guix_pin_doesnt_support_channelsscm/">[link]</a></span> &#32; <span><a href="https://www.reddit.com/r/GUIX/comments/q0rvpd/guixjupyters_guix_pin_doesnt_support_channelsscm/">[comments]</a></span>
