Hello,My name is Long. Description: version:newest(2aaf469) bazel:0.27.0 ubuntu:16.04 ndk:r17c opencv:3.4.1(from source code include origin and contrib)

this is my Error: long@long:/media/long/data/android/mediapipe$ bazel build -c opt --config=android_arm64 mediapipe/examples/android/src/java/com/google/mediapipe/apps/facedetectiongpu ERROR: /media/long/data/android/mediapipe/third_party/BUILD:24:1: no such package '@android_opencv//': java.io.IOException: Error downloading [https://sourceforge.net/projects/opencvlibrary/files/4.0.1/opencv-4.0.1-android-sdk.zip/downl oad] to /home/long/.cache/bazel/_bazel_long/2855d1951dc2684b853376a37e34b96b/external/android_opencv/download.zip: connect timed out and referenced by '//third_party:opencv' ERROR: Analysis of target '//mediapipe/examples/android/src/java/com/google/mediapipe/apps/facedetectiongpu:facedetectiongpu' failed; build aborted: Analysis failed INFO: Elapsed time: 16.197s INFO: 0 processes.

Can I use version 3.4.1 of opencv? Is it possible not to upgrade? thx.

Hi Long, the error you pasted above is more like a network issue. More specifically, your machine is not able to download the pre-compiled OpenCV android SDK from https://sourceforge.net/projects/opencvlibrary/files/4.0.1/opencv-4.0.1-android-sdk.zip/download. Unfortunately, we use the pre-compiled OpenCV Android SDK directly, rather than building the libraries from source.

Could you verify that you can access https://sourceforge.net/projects/opencvlibrary/files/4.0.1/opencv-4.0.1-android-sdk.zip/download? If so, can you retry the build command?

i can acces your website. now i try it again. and generate a new Error: INFO: Call stack for the definition of repository 'FP16' which is a third_party_http_archive (rule definition at /home/long/.cache/bazel/_bazel_long/2855d1951dc2684b853376a37e34b96b/external/org_tensorflow/third_party/repo.bzl:206:28):
