Just find why tensorflow is failing to compile.

Package signature is wrong in 

./sources/poky/meta/recipes-vmais/tensorflow/tensorflow_1.13.1.bb

This file points to this repository

git://github.com/tensorflow/tensorflow.git;branch=r1.13

Inside this repository , the file tensorflow/third_party/icu/workspace.bzl

https://github.com/tensorflow/tensorflow/blob/r1.13/third_party/icu/workspace.bzl

def repo():
	third_party_http_archive(
	name = "icu",
	strip_prefix = "icu-release-62-1",
	sha256 = "e15ffd84606323cbad5515bf9ecdf8061cc3bf80fb883b9e6aa162e485aa9761",
	urls = [
	"https://mirror.bazel.build/github.com/unicode-org/icu/archive/release-62-1.tar.gz", URL DOES NOT EXIST
	"https://github.com/unicode-org/icu/archive/release-62-1.tar.gz", THIS ONE HAS DIFFERENT SHA256 SIGNATURE.
	],
	build_file = "//third_party/icu:BUILD.bazel",
	system_build_file = "//third_party/icu:BUILD.system",
	patch_file = clean_dep("//third_party/icu:udata.patch"),
	)

I am checking that branch r1.15 has the right file and the right signature.

I have the same problem here, recipe or binary had changed . Everything was compiling ok a few days ago.

I am trying to solve this problem:

yocto_rootfs_v3/build/tmp/work/aarch64-poky-linux/tensorflow/1.13.1-r0/bazel/output_base/external/icu/release-62-1.tar.gz: Checksum was 86b85fbf1b251d7a658de86ce5a0c8f34151027cc60b01e1b76f167379acf181 but wanted e15ffd84606323cbad5515bf9ecdf8061cc3bf80fb883b9e6aa162e485aa9761 and referenced by '//tensorflow/core/kernels:string_util

Please build eiq first then build tensorflow

$ flex-builder -c eiq               # build all eIQ components (include armnn, tensorflow, tflite, opencv, onnx, etc
$ flex-builder -c tensorflow    # build tensorflow

Hi Yiping,

I tried to build eiq on different computers and different networks. Eiq still failed to be built at tensorflow.

Cheers,

Mason

According to LSDK 20.04 user manual, Cross-build eIQ components on host

$ flex-builder -c eiq # build all eIQ components (include armnn, armcl, tensorflow, tflite, opencv, onnx, etc)

$ flex-builder -c armnn # build armnn

$ flex-builder -c tensorflow # build tensorflow

$ flex-builder -c tflite # build tflite

$ flex-builder -c opencv # build opencv

$ flex-builder -c caffe # build caffe

$ flex-builder -c onnx # build onnx

$ flex-builder -c onnxruntime # build onnxruntime
