can not initialize imagenet

Hi I am following the steps posted here:

the build was smooth and error free, but here are the error messages when I tried the first example. Other examples generate similar error messages:

Hi blp_engineer, it would seem that your Googlenet model is corrupted - can you try the steps from this post to see if it helps?

I have the same problem and I did try everything from the link and it still doesn’t work. Please let me know if there are any alternative.

Are you able to run any other networks, either image recognition or object detection?

$ ./imagenet-console orange_0.jpg test.jpg alexnet
$ ./imagenet-console orange_0.jpg test.jpg googlenet_12

Let us know if the output is any different trying these. And you can try object detection:

$ ./detectnet-console peds-004.jpg test.jpg
$ ./detectnet-console dog_1.jpg test.jpg coco-dog

Also can you run “ls -ll” command from the data/networks folder and check the sizes of the models to confirm they match?

~/workspace/jetson-inference/data/networks$ ls -ll

I couldn’t get detectnet to work as well. I checked the networks folder and it seems like I lack a lot of the files there. Here is what I have:

If you could, could you tell me how to get other files? Thank you

Ah yes, I see, you are missing files and the models that you do have aren’t the correct size, so they didn’t download properly. As a test, try running these commands to re-download them from the original source:

$ cd jetson-inference/data/networks/
$ wget -O googlenet.prototxt
$ wget -O bvlc_googlenet.caffemodel

Then check “ls -ll” again - your bvlc_googlenet.caffemodel should be 53533754 bytes and googlenet.prototxt should be 35861 bytes. If sizes match, try re-running imagenet-console again.

To re-download all the models, clear your build directory and re-run cmake:

$ cd jetson-inference
$ rm -r -f build
$ mkdir build
$ cd build
$ cmake ../
$ make
$ sudo make install

Thank you! I was able to get it to work thanks to your help. I realize that after you re-run cmake and make, it corrupts the caffemodel. So it’s after make that you then you download the source. If you download first then cmake it would just corrupt the caffemodel again.

Much appreciate it!

for users in China, is blocked, so your options:

  1. get a router with VPN.
  2. download the file to a computer with VPN.
  3. enable internetsharing on your computer with VPN, and let NANO access the internet through your machine.

Any other options?
