I used the following code in Python:&lt;\/div&gt;&lt;div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;import sys&lt;\/div&gt;&lt;div&gt;sys.path.append(r&#8221;C:\\Program Files\\Lumerical\\v241\\api\\&lt;wbr&gt;python&#8221;)&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;import qinterconnect&lt;\/div&gt;&lt;div&gt;from qinterconnect.solver import QSolver&lt;\/div&gt;&lt;div&gt;from matplotlib import pyplot as plt&lt;\/div&gt;&lt;div&gt;import numpy as np&lt;\/div&gt;&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;But I get this error :&nbsp;&nbsp;ModuleNotFoundError: No module named &#8216;qinterconnect.solver'&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;&lt;p&gt;I have attached a screenshot from the&nbsp;<em>Program Files<\/em> Lumerical folder, which shows that it seems Python API module for qINTERCONNECT is installed. However, it does not appear to contain any solver, such as QSolver, so I am unsure if this error is related to that.&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/04-11-2024-1730745924-mceclip0.png\" \/> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/04-11-2024-1730745980-mceclip2.png\" \/>&lt;\/p&gt;&lt;p&gt;Additionally, I have attached a screenshot from the Ansys Lumerical Launcher, which shows that I have access to qINTERCONNECT. However, when I try to open this solver, I only see a command window instead of a specific interface GUI, like with the other solvers. I have attached this screenshot as well.&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/04-11-2024-1730745991-mceclip3.png\" \/>&lt;\/p&gt;&lt;p&gt;I would appreciate it if you could let me know how I can resolve this issue.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;In the meantime, I tried using INTERCONNECT to simulate the Hong-Ou-Mandel&nbsp;effect, but it seems unable to solve it and returns values in the classic view. Although I used an attenuator with -80 dB, I still could not observe the Hong-Ou-Mandel effect in the output.&lt;\/p&gt;&lt;\/div&gt;&lt;div&gt;I have attached my setup screenshot in interconnect, I used optical oscilloscopes in both outputs and also tried optical power meters in both outputs. I see the same result from both outputs and I could not observe the HOM effect.&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/04-11-2024-1730746058-mceclip4.png\" \/>&lt;\/div&gt;<\/p>\n","protected":false},"template":"","class_list":["post-392662","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["141.215.101.240"],"_btv_view_count":["635"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1731374614:344016"],"_bbp_subscription":["3002","344016","4274"],"_bbp_topic_id":["392662"],"_bbp_forum_id":["27833"],"_bbp_engagement":["3002","4274","344016"],"_bbp_voice_count":["3"],"_bbp_reply_count":["21"],"_bbp_last_reply_id":["394122"],"_bbp_last_active_id":["394122"],"_bbp_last_active_time":["2024-11-15 19:33:49"]},"test":"venuskdumich-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/392662","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/392662\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=392662"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
