After forcing the Jetson OS (based on the ubuntu 18.04) to have Python 3.8 running. After having the JetPack 4.6.3 installed in the Jetson Nano Jetson OS.<\/p>\n\n\n\n

When attempting to install TensorFlow 2+ manually in the Jetson Nano based on Official TensorFlow for Jetson Nano! – Jetson & Embedded Systems \/ Jetson Nano – NVIDIA Developer Forums<\/a><\/p>\n\n\n\n

\"\"
Running the installation in Jetson Nano<\/figcaption><\/figure>\n\n\n\n

Or running the pip3 install command:<\/p>\n\n\n\n

sudo pip3 install --pre --extra-index-url https:\/\/developer.download.nvidia.com\/compute\/redist\/jp\/v46 tensorflow<\/code><\/pre>\n\n\n\n
After a long time installing all the dependency for TensorFlow. A dreaded error message will occur.<\/p>\n\n\n\n
\n
ERROR: Failed to build installable wheels for some pyproject.toml based projects (h5py)<\/p>\n<\/blockquote>\n\n\n\n
\"\"
ERROR: Failed to build installable wheels for some pyproject.toml based projects (h5py)<\/figcaption><\/figure>\n\n\n\n
To understand the error, scroll up to read what are the error.<\/p>\n\n\n\n\n\n\n\n
The first error message scrolling up suggest the version of hd5 are not supported.<\/p>\n\n\n\n
\"\"
Loading library to get build settings and version: \/usr\/lib\/aarch64-linux-gnu\/hdf5\/serial\/libhdf5.so the details<\/figcaption><\/figure>\n\n\n\n
Scroll higher, the error was triggered when pip is building the h5py dependency\/library.<\/p>\n\n\n\n
\"\"
h5py fail, it is a dependency for tensorflow<\/figcaption><\/figure>\n\n\n\n
Hence, forming the problem statement, h5py library for Python 3.8 cannot be installed due to the binary hdf5 of Jetson OS is version 1.10.0.<\/p>\n\n\n\n
First approach will be updating the Jetson OS using apt-get to update the Jetson OS hdf5 library to at least version 1.10.0<\/p>\n\n\n\n
First attempt used based on command:<\/p>\n\n\n\n
sudo apt-get install libhdf5-serial-dev hdf5-tools libhdf5-dev<\/code><\/pre>\n\n\n\n
\"\"
The hdf5 library is already up to date<\/figcaption><\/figure>\n\n\n\n
First attempt does not work, as minor version was not added to the repositories of dated Jetson OS (based on Ubuntu 18.04).<\/p>\n\n\n\n
Second attempt, build the hd5 python library via source. Based on idea offered at Installation \u2014 h5py 3.13.0 documentation<\/a><\/p>\n\n\n\n
\"\"
Following the h5py documentation<\/figcaption><\/figure>\n\n\n\n
\"\"
Continue with the documentation, didn’t bothered setting up git correctly but it still works<\/figcaption><\/figure>\n\n\n\n
\"\"
Typo error but not the reason of build failure<\/figcaption><\/figure>\n\n\n\n
\"\"
Error suggested that numpy was not install into the Python 3.8<\/figcaption><\/figure>\n\n\n\n
\"\"
Install numpy<\/figcaption><\/figure>\n\n\n\n
After numpy is installed, proceed to build the h5py, but encountered a different error.<\/p>\n\n\n\n
\"\"
New error, not old error means progress<\/figcaption><\/figure>\n\n\n\n
\"\"
Python.h were not found<\/figcaption><\/figure>\n\n\n\n
The second attempt, the error encounter suggesting that the gcc compiler was not able to find header file, the Python.h during its compilation. Hence error.<\/p>\n\n\n\n
After taking some time to research, installing python without the development tool kit will not able to help compilation due to missing header.<\/p>\n\n\n\n
To fix this error, install the proper development library into Jetson OS.<\/p>\n\n\n\n
sudo apt install libpython3.8-dev<\/code><\/pre>\n\n\n\n
\"\"
Recompiling immediately after installation of the Python 3.8 development library, and h5py compiled and created<\/figcaption><\/figure>\n\n\n\n
H5PY_SETUP_REQUIRES=0 pip3 install . --no-deps --no-build-isolation<\/code><\/pre>\n\n\n\n
Lets rerun the installation attempt to reinstall the TensorFlow.<\/p>\n\n\n\n
sudo pip3 install --pre --extra-index-url https:\/\/developer.download.nvidia.com\/compute\/redist\/jp\/v46 tensorflow<\/code><\/pre>\n\n\n\n
\"\"
h5py which is manually compiled are detected and accepted by pip3<\/figcaption><\/figure>\n\n\n\n
\"\"
TensorFlow installation successful<\/figcaption><\/figure>\n\n\n\n
Real test to validate TensorFlow successful installation works.<\/p>\n\n\n\n
\"\"
It works<\/figcaption><\/figure>\n\n\n\n
And installing TensorFlow on dated Jetson Nano for the Jetson OS is challenging. It will help if a person has knowledge of Ubuntu, Python library management. The part that was left out was how to install Python 3.8<\/a>.<\/p>\n\n\n\n
