Error building "Getting Started" example: rebuild TensorFlow with the appropriate compiler flags

[natemurthy]

I'm trying to run the example from the "Getting Started" guide (https://github.com/galeone/tfgo#getting-started) on my MacBook, but after installing the prebuilt TensorFlow C library and tfgo, updating my links, and attempting to build and run the example I encounter this error:

2023-01-21 19:01:59.670541: I tensorflow/core/platform/cpu_feature_guard.cc:193] This TensorFlow binary is optimized with oneAPI Deep Neural Network Library (oneDNN) to use the following CPU instructions in performance-critical operations:  AVX2 FMA
To enable them in other operations, rebuild TensorFlow with the appropriate compiler flags.

I'm guessing I'll have to build the TensorFlow C library from scratch. Is that what this implies, are could there be another solution that doesn't involve having to do this?

Seems to be related: #47 (comment)

Hi, it looks like you're running on an M2 mac (thus ARM architecture), but the library is built for x86_64 (there's no pre-built library for arm64 https://www.tensorflow.org/install/lang_c).

I have no experience with mac, but for sure you need to use things binary compatible. Hence, or you find a way to re-compile TensorFlow for ARM64 (but I guess it's not possible, otherwise google would have already provided the pre-built library), or you use Go built for x86_64.

I suggest you to open an issue on the TensorFlow repository since it's not something purely tfgo related, but everything depends on the TensorFlow C library

[natemurthy]

Hm, definitely not an M2 on this old clunky Mac 🙃

[galeone]

can you try to build a simple C program that uses the TensorFlow C library? In this way we can understand if it's related to Go or if it's related to the library provided and your OS (btw I still think this is TensorFlow specific issue, not tfgo)

[natemurthy]

Yes, I successfully built this C program: https://github.com/natemurthy/go-playground/blob/main/tfgo/hello_tf.c

nate:tfgo$ gcc hello_tf.c -ltensorflow -o hello_tf
nate:tfgo$ ./hello_tf 
Hello from TensorFlow C library version 2.11.0
