[JackieYelich]

I followed your install step "2.2. Build for aarch64 Linux (Jetson Nano, Raspberry Pi)"
but this error occurred
how can i fix it?

tony@Mediapipe-JetsonNano:$ chmod 755 bazel-3.1.0-installer-linux-x86_64.sh
tony@Mediapipe-JetsonNano:$ sudo ./bazel-3.1.0-installer-linux-x86_64.sh

Did Jetson nano use "bazel-3.1.0-installer-linux-x86_64.sh"?
but Jetson nano is aarch64 Linux architecture

At first, 2.2.1. build TensorFlow Lite library on Host PC.
And then, 2.2.2. copy Tensorflow Lite libraries to target Jetson / Raspi.

Thank you, I implemented successful.
By the way, could this repository implement on Win10?

Hey, I have the same problem as you.How did you solve it？

Hi, I have met many issues when building the library on Jetson. so may you share the file you had build on the Jetson Nano.(libtensorflowlite_gpu_delegate.so&libtensorflowlite.so).

best regards,

What is the exact path? I cannot find /home/jetson/lib as mentioned in document, thanks.
