Hi @mertall, I suspect the issue is that SX was added in recent commits, and not been released yet. If you try installing from github directly it should work, if not let me know! |

Hey @jcmgray I did indeed pull directly from GitHub within the collab. This seems to only occur when trying in collab. I got it running on a local Jupyter notebook. Not sure why collab can't pick up that there are SX gates. |

For clarity within collab I made sure to uninstall quimb and then pip install via GitHub url. But still wasn't able to resolve |

I don't seem to have any problems on colab if I do : And then (let me know if you have some other short snippet that demonstrates the problem): import quimb.tensor as qtn
circ = qtn.Circuit(1)
circ.sx(0)
circ.psiMy guess is that despite trying to uninstall |

Awesome. Thanks for digging into it. I'll try again. |

Hi,
I have been experimenting with Quimb with "peak circuits". I am trying to run the program with a GPU on google collab. I run into an issue when I pull the code directly from GitHub, as I need logic for SX gate.
`/usr/local/lib/python3.11/dist-packages/quimb/tensor/circuit.py in parse_openqasm2_str(contents)
314 qubits = tuple(
315 sitemap[qubit.strip()] for qubit in qubits.split(",")
--> 316 )
317 gates.append(Gate(label, params, qubits))
318 continue
/usr/local/lib/python3.11/dist-packages/quimb/tensor/circuit.py in init(self, label, params, qubits, controls, round, parametrize)
1170 **gate_opts,
1171 ):
-> 1172 if contract in ("auto-mps", "nonlocal"):
1173 _apply_controlled_gate_mps(psi, gate, tags=tags, **gate_opts)
1174 elif contract in (
ValueError: Unknown gate: SX.`
I am not sure how to resolve this error, I see the SX gate in the package contents. I looked at the logic for _apply_cntrolled_gate_mps... One thought I had was adding SX to the tag excplicity as a param during the add gate logic.
Looking forward to your thoughts!
