It demonstrates how to use mostly python code to optimize a caffe model and run inferencing with TensorRT. The new code should mostly work on Jetson TX2 still. If you want to access my previous code which was verified against tensorflow That did not work too well. There were several problems. Secondly, tensorflow kept reporting errors like the following ones. When I switched to tensorflow By doing that, the computations in NonMaximumSuppression were reduced a lot and the model ran much faster.

Testing with tensorflow Hopefully, I will be able to share more experience on that soon. Install OpenCV 3. Install TensorFlow 1. Use this pip wheel for JetPack Clone the code from my GitHub repo. Run the installation script. In case of image file, the script would do inferencing using the same image over and over again.

So the --build action only needs to be done once for each model to be used. Later invocations of the script could load the optimized graph directly and thus saves execution time. Here is the help message of the script.Serial-ATA drives are used in many desktop and laptop computers. Also, SATA drives are relatively inexpensive for the amount of storage they hold. You can simply use the SATA drive as supplemental storage, or choose to use the drive as the root directory of the operating system.

This method is a mostly GUI solution, there are command line equivalents that others may use and are more sophisticated.

Because the installation demonstration is using mostly GUI tools, please refer to the video for the walk through. Here are the basic steps:. Make sure that the Jetson is powered down, and disconnect the power. However, this can be rather precarious as the SSD can act as a big lever which when bumped may and break off the connector from the TX2 carrier board.

Adding a cable minimizes this risk. Format the SATA drive by adding at least one partition with a ext4 format. There are a couple of ways of doing this, an easy way is to use the Disks application which provides a GUI for formatting disks.

In the L4T Remember how this was good clean fun? Not so much as a few blue words were sprinkled in before using a Terminal to cast the magic incantation:. This creates a partition on the SSD. Format the disk using ext4 afterwards. Next, mount the SATA drive. Now enjoy the sea of GB goodness.

In the video we talked a little about different technologies used in SSDs.

Any idea or suggestion for that? There could be one of several issues. Thanks for reading! Hi, I have a question about it too. I have installed ssd on tx2, and I add a SSD. I did all the format, of the disk, and I follow your instruction, until… the reboot. When I reboot, I loss the signal on my screen. Do you have an explanation, that could explain that? It is difficult to help debug this issue from your description. My advice is to watch the boot sequence using the serial console.

Follow the documentation from the TensorFlow models repository. Once you have obtained a checkpoint, proceed with building the graph and optimizing with TensorRT as shown above. As a convenience, we provide a script to download pretrained model weights and config files sourced from the TensorFlow models repository.

Important: Some of the object detection configuration files have a very low non-maximum suppression score threshold ie. This can cause unnecessarily large CPU post-processing load. Depending on your application, it may be advisable to raise this value to something larger like 0. We do this for the above benchmark timings. The parameter can be found for example in this line.

Some config parameters may be modified, such as the number of classes, image size, non-max supression parameters, but the performance may vary. Skip to content.

Aug 1, Note: This article has been updated for L4T This is the third in a series of short articles about running the Jetson TX1 from external storage. Looky here:. SATA drives are used in many desktop and laptop computers. Also, SATA drives are relatively inexpensive for the amount of storage they hold.

You can simply use the SATA drive as supplemental storage, or choose to use the drive as the root directory of the operating system. This method is a mostly GUI solution, there are command line equivalents that others may use and are more sophisticated. Embedded systems tend to be simpler and more direct. While there are several different strategies used, the Jetson TX1 uses the extlinux boot loader. By modifying the file extlinux. Because the installation demonstration is using mostly GUI tools, please refer to the video for the walk through.

Here are the basic steps:. However, this can be rather precarious as the SSD can act as a big lever which when bumped may break off the connector from the TX1 carrier board. Adding a cable minimizes this risk. Format the SATA drive by adding at least one partition with a ext4 format.

The partition size must be at least 16GB. There are a couple of ways of doing this, an easy way is to use the Disks application which provides a GUI for formatting disks. Next, mount the SATA drive. On the other hand, if you want to use the SSD as your root directory you copy the contents from the root directory of the internal flash memory to the SATA drive. In the video example:. For a nearly full internal flash memory, this will take about 3 minutes depending on the speed of the SATA drive.

The last setup step is to modify the file extlinux. An editor will open on the configuration file. Duplicate the eMMC entry usually named primaryand change the entries as shown in the video. One of the major changes indicates the device and partition, which is:. Note: If the machine does not boot, hook up a serial console to a host and examine the boot sequence. The entries that you have changed should show up in the boot options. Once the machine boots, you should run some typical programs or compiles to make sure everything works and is installed correctly.

There are some things to watch out for, such as checking to make sure that system level settings for things such as swap files are correct. In general, it is a copy of the internal eMMC, so it should all pretty much behave itself. You may see error messages on the screen or console that it is looking for a boot drive. If the root SATA drive is not available for some reason, you can use the serial console to select the internal eMMC as the boot device.

That will allow you to edit the extlinux. I would advise keeping a bootable SD card around in case something really goes wrong. The number following the sda e. Thanks for reading! Do you mean in the case that you are using the SSD as extra storage, or as the root? Personally, I use the Disks program to help, similar to how was done on the TK1.

The M. There are several different sizes and brands of these types of devices, people have reported good results with the Samsung variety. We also use our trusty iFixit Pro Tech Toolkit which contains a variety of useful tools for just this purpose. The Southern California weather brought in Santa Ana winds during filming.

There seems to be a lot of static electricity hanging about, so it is time to break out the iFixit Anti-Static Mat. This helps keep the ESD dogs at bay. If in doubt when working on electronics especially at the component levelthe anti-static mat is your friend.

You will need to detach the carrier board from the Jetson Xavier Module. This is a straightforward task. With a 2 phillips head screwdriver, remove the four screws that hold the standoffs to the Jetson module the carrier board is sandwiched in-between.

From the factory, the screws may have some blue thread locker on them, which may require a little elbow grease to start the removal process. Set the standoffs and screws aside. Next, carefully disconnect the carrier board from the module. Note that there is a wire connecting the module to the carrier board this is for controlling the fan. The wire is relatively short and the connection is delicate. There is a pin connector which joins the the Jetson module to the carrier board.

As shown in the video, lift gently on the carrier board. The PCIe connector on the end of the carrier board can provide a little purchase, but you should not have to apply an excessive amount of pressure to break the connection. Lift gently and find the wire connecting the carrier board to the module.

The wire is not long enough to allow the carrier board to lay flat on a table surface when the Jetson module is in certain positions. As shown in the video, you can use something like a book to create a resting place for the carrier board. An alternative is to simply lay the Jetson module on its side, with the cable exiting on the bottom side. You may want to disconnect the cable from the carrier board.

You can use a pair of tweezers to help in the task. The connector is delicate, personally I would try to avoid doing that if possible. A retaining screw is provided at the end of the M. Remove the retaining screw.
