py39-tensorflow +native : dependencies are broken

[mouse07410 (Mouse)]

Big Sur 11.2.3, Xcode-12.4. Attempt to install py39-tensorflow +native, installation fails because of conflicting dependencies: it seems to require both bazel-3.1 and bazel-3.7.

OK, the issue is py-tensorflow requires bazel-3.1 to build, but tensorflow-addons which it now requires uses bazel-3.7. A the main tensor flow port has to use 3.1, it rejects 3.7, I think the fix is to change the adding package to use the same.

[Chris Jones <jonesc@…>]

In fb91bc5fdf64141b6aeeb0f1e7121cca20a1e5a9/macports-ports (master):

py-tensorflow-addons: Use bazel 3.1 to build to match py-tensorflow
Closes: #62685

With the fix applied - py39-tensorflow-addons fails to configure:

yeah, a bit of a issue with the dependencies. should be fixed now I hope ?

[mouse07410 (Mouse)]

Well, that part was fixed, but it still fails the build.

From your log it appears you have issues downloading targets. You should check your network settings etc...

Also, although I don't see why it would cause this, you have in your log

:warn:main The macOS 11.2 SDK does not appear to be installed. Ports may not build correctly.
:warn:main You can install it as part of the Xcode Command Line Tools package by running `xcode-select --install'.

please also try resolving the above issue and try again.

Something else. You are using a non-MacPorts provided Java JDK 11

:debug:build JAVA_HOME='/Library/Java/JavaVirtualMachines/amazon-corretto-11.jdk/Contents/Home'

and it looks like that is the cause of the problems, i.e.

The problem is with the Web proxy (this all is happening behind a corporate firewall). Are you saying that the Macports-provided JDK-11 would understand proxy env vars from Macports config or from the environment, but the Amazon port of JDK-11 would not???

Same thing, of course - it does not take the env var JAVA_HOME, but chooses to figure it out for itself instead:

Ah yes. i guess you are using the last released version of base ? I am using a devel version from git which I think has a work around for this.

I have no idea. I was just noting you where using a JDK that isn’t the one normally used, or tested to build the port.

Please try removing that, and then allow the port to install the fallback from Macports...

Env vars are set to point at the proxy:

How would you suggest I debug it?

Sorry but I am not really an expert on JAVA so I cannot help you with your proxy settings...

[cjones051073 (Chris Jones)]

Btw, not really a fix but a side comment, but there is now a new port that provides a hardware accelerated build of tensorflow, from Apple, for macOS11. See py38-tensorflow_macos. Only slight issue is upstream does not yet (its an alpha version right now) support python 3.9, so there is only a 3.8 version at the moment.

See

port notes py38-tensorflow

For migration instructions.

Thank you! So, for now I should look at py38-tensorflow_macos, and eventually there'd be py39-tensorflow_macos?

That should work. And py38-tensorflow_macos installs smoothly.

Update Would you be able to report the proxy problem upstream? It seems obvious that their (bazel's) downloader is broken. How do I know? Because jarsigner on my machines can access the external time-servers via HTTP and HTTPS through the proxy just fine.

Replying to mouse07410:

That entirely depends on if/when upstream support 3.9

​https://github.com/apple/tensorflow_macos

That should work. And py38-tensorflow_macos installs smoothly.
