[Solved] Failed to install NDK/Caffe prerequisites

Hi

I am looking into this now. So far I haven't been able to reproduce it. 

It is possible this is a transient problem with the repository. Can you retry?

I am able to fetch the package manually using 

wget http://cn.archive.ubuntu.com/ubuntu/pool/universe/p/python-xdo/python3-xdo_0.4-2_all.deb

Are you able to fetch it in this way?

I see from your profile and the URL of the package that you are in China, I think we have sometimes seen issues with repositories not being accessible from machines in China. I am contacting some of our colleagues in China to see if they see this problem and if they have a workaround.

If you are still unable to run the command 

sudo apt-get install python3.x

 could you attach a copy of your /etc/apt/sources.list so that I can try and reproduce the problem here.

Thanks.

Paul

Hi @hight 

Apparently it seems an issue related to apt/sources.list.

It is possible that the source.list is corrupted.

You can try the following:

1. Remove the file: sudo rm /etc/apt/sources.list
2. Create an empty one: sudo touch /etc/apt/sources.list
3. Restore the default settings using "Software & Updates" tool (see attached image)

Hi,

I have changed sources.list (/etc/apt/sources.list). The problem about fetch has been resolved.

All packages can be installed successfully, including "native compilation tools","NDK/Caffe prerequisites","Tensorflow","Cross-compilation".

The sources.list I used in HOST is local source (By modify through vim). Also you can try to change it by the method of @luispimo

Hello,

I am still having trouble with passing the TensorFlow to the CAFFE to IMG-NNVM conversion tests. Below is a screenshot  of the error I am getting.

Your help is truly appreciated.

Hi,

That looks like caffe was not successfully installed during the setup process. The failure to install it is likely visible further up the console log. If you could either scroll up to show that, or run the installer capturing the console output to a file it would be helpful. You can do that using the tee command as shown below

devtools.run 2>&1 |tee /tmp/output.txt

Thank you for your reply.

Best,

Hi, @yasmine. I don't see an attachment...

@paulbuxton @Yasmine

Try different file formats, the Forum system rejects some. I think JPEGs are OK. And .PNGs

What we actually want is a text file. The console output will be more than can easily fit onto a single screen and we cannot search an image for error strings.

Text files .txt are OK

W: Skipping acquire of configured file 'bionic-updates/main/dep11/Components-amd64.yml' as repository 'http://archive.ubuntu.com/ubuntu jammy InRelease' doesn't have the component 'bionic-updates/main' (component misspelt in sources.list?)

We are receiving several warnings as in the above while running sudo add-apt-repository "http://archive.ubuntu.com/ubuntu bionic-updates/main"

any suggestion is appreciated.

Hi I beleive this this is because you are using Ubuntu 22.04, the requirements for the NCSDK are 18.04 or 20.04 (jammy indicates the Ubuntu version is Jammy Jellyfish which is the codename for Ubuntu22.04).

@paulbuxton  Thank you for the explanation. we suspected the version problem, but wanted to give it a try since the Tutorial mentions "Ubuntu Development Platform
x86-64 PC with a minimum 4GB RAM running Ubuntu 18.04 with a Micro SD Card slot (or USB connection to a Micro SD Card Adapter)", but 20.04 also works . why not give it a try with 22.04 :).

We will go back to 20.04. But,  just to clarify, from your explanation we conclude the warnings are not to be ignored. they are indeed problem. Please confirm.

Many thanks.

Yes those will likely cause a problem in addition I am told by the NCSDK team that there are other less obvious issues that pop up when using Ubuntu 22.04 I recently downgraded my own installation because of this.

There is an intention to update to a more up to date Ubuntu and drop 18.04 (as it is 4 years old now!), but I don't have any information on when that will be.
