guberti opened a new issue, #11811: URL: https://github.com/apache/tvm/issues/11811
The tutorial `gallery/how_to/work_with_microtvm/micro_train.py` demonstrates how transfer learning can be used to train special models that fit on microcontrollers (and can be compiled and autotuned with TVM). As part of this, it downloads the Stanford Cars dataset from https://ai.stanford.edu/. Unfortunately, https://ai.stanford.edu/ went down around 2:30 PST on Jun 21. This caused the link to download the dataset to go offline as well. Since every run of the CI rebuilds the documentation and runs this training, it caused the CI to start failing as well: (from https://ci.tlcpack.ai/blue/organizations/jenkins/tvm/detail/main/3605/pipeline): ``` [2022-06-21T23:10:04.975Z] Unexpected failing examples: [2022-06-21T23:10:04.975Z] /workspace/gallery/how_to/work_with_microtvm/micro_train.py failed leaving traceback: [2022-06-21T23:10:04.975Z] Traceback (most recent call last): [2022-06-21T23:10:04.975Z] File "/workspace/gallery/how_to/work_with_microtvm/micro_train.py", line 170, in <module> [2022-06-21T23:10:04.975Z] "http://ai.stanford.edu/~jkrause/car196/cars_train.tgz";, f"{FOLDER}/images/target.tgz" [2022-06-21T23:10:04.975Z] File "/usr/lib/python3.7/urllib/request.py", line 247, in urlretrieve [2022-06-21T23:10:04.975Z] with contextlib.closing(urlopen(url, data)) as fp: [2022-06-21T23:10:04.975Z] File "/usr/lib/python3.7/urllib/request.py", line 222, in urlopen [2022-06-21T23:10:04.975Z] return opener.open(url, data, timeout) [2022-06-21T23:10:04.975Z] File "/usr/lib/python3.7/urllib/request.py", line 525, in open [2022-06-21T23:10:04.975Z] response = self._open(req, data) [2022-06-21T23:10:04.975Z] File "/usr/lib/python3.7/urllib/request.py", line 543, in _open [2022-06-21T23:10:04.975Z] '_open', req) [2022-06-21T23:10:04.975Z] File "/usr/lib/python3.7/urllib/request.py", line 503, in _call_chain [2022-06-21T23:10:04.975Z] result = func(*args) [2022-06-21T23:10:04.975Z] File "/usr/lib/python3.7/urllib/request.py", line 1352, in http_open [2022-06-21T23:10:04.975Z] return self.do_open(http.client.HTTPConnection, req) [2022-06-21T23:10:04.975Z] File "/usr/lib/python3.7/urllib/request.py", line 1326, in do_open [2022-06-21T23:10:04.975Z] raise URLError(err) [2022-06-21T23:10:04.975Z] urllib.error.URLError: <urlopen error [Errno 110] Connection timed out> ``` This dataset is 2GB in size, and cannot be easily mirrored on `tlcpack`. -- This is an automated message from the Apache Git Service.
