Starting Vitis-AI docker #347

Closed nevilshah235 closed 3 years ago

docker: Error response from daemon: error while creating mount source path '/opt/xilinx/dsa': mkdir /opt/xilinx: read-only file system.

Hi @nevilshah235 ,

Can you check that the user account that you use to run Vitis AI docker has write permissions to /opt/xilinx ?

nevilshah235 commented 3 years ago

Hi @hanxue

Thank you for the support. I tried running it with sudo as well. But still I get the same error. Screenshot from 2021-03-26 11-51-58

hanxue commented 3 years ago

Hi @nevilshah235 ,

Hmm, the error seems to be no write permission to /opt/xilinx, or /opt. Could you do me a favour and paste the output of the following commands

df -hTl
ls -ld /opt/xilinx
ls -ld /opt

?

nevilshah235 commented 3 years ago

Sure.

The /opt directory looks OK. Can you please list out the contents of

ls -l /opt/xilinx

please?

Just to ensure the problem is due to this directory, temporarily delete this line in your local copy of docker_run.sh https://github.com/Xilinx/Vitis-AI/blob/master/docker_run.sh#L87

    -v /opt/xilinx/dsa:/opt/xilinx/dsa \
hanxue commented 3 years ago

A quick question. Are you by any chance running Docker inside a Mac or Windows machine?

We have seen weird mount issues like these, and at the moment Vitis AI is only supported on a Linux host with Docker.

nevilshah235 commented 3 years ago

Hi @hanxue

I also deleted line no. 88 in my local installation of docker_run.sh -v /opt/xilinx/overlaybins:/opt/xilinx/overlaybins \

After that I was able to successfully run the docker_run.sh script

I am using an Ubuntu 20.04 OS. Screenshot from 2021-03-26 17-06-21

nevilshah235 commented 3 years ago

Sharing the output of ls -l /opt/xilinx I had created the directory dsa, to check whether it works after I include that directory, but same issue is there

Which workflow are you using? If it is Whole App Acceleration or Alveo related, you will need to have XRT installed on your host. Download it from https://www.xilinx.com/products/design-tools/vitis/xrt.html#gettingstarted

This version should work

https://www.xilinx.com/bin/public/openDownload?filename=xrt_202020.2.9.317_18.04-amd64-xrt.deb

You might want to delete /opt/xilinx/dsa that you created prior to installing XRT.

nevilshah235 commented 3 years ago

Thanks for the fix suggestion. I am unable to install XRT library on Ubuntu 20.04, due to problems with prerequisite libraries. The packages required have different version numbers. So I had not installed XRT earlier, still facing the same issue.

There are a couple of options for installing XRT for Ubuntu 20.04:

Download from https://www.xilinx.com/bin/public/openDownload?filename=xrt_202020.2.9.317_20.04-amd64-xrt.deb

Build and install XRT from source per the instructions https://xilinx.github.io/XRT/2020.1/html/build.html . i.e. Download the XRT 2020.2 official release from https://codeload.github.com/Xilinx/XRT/tar.gz/refs/tags/202020.2.8.743 , and within the XRT source directory, there is a src/runtime_src/tools/scripts/xrtdeps.sh script that will install all the required tools.

nevilshah235 commented 3 years ago

Hi @hanxue

I installed XRT, but it's still not working. Earlier when I had tested, I forgot to add -v /opt/xilinx/dsa:/opt/xilinx/dsa \ -v /opt/xilinx/overlaybins:/opt/xilinx/overlaybins \ in the docker_run.sh script, so the installation worked fine. But I am still facing the same issue as mentioned earlier in starting VITIS-AI docker.

hanxue commented 3 years ago

Hi @nevilshah235 ,

What is the exact error you are seeing? Is it the following? 

docker: Error response from daemon: error while creating mount source path '/opt/xilinx/dsa': mkdir /opt/xilinx: read-only file system.

At this point , it is easier to verify if there is something wrong with the Docker installation

  1. Trying running Vitis AI docker on another machine, even if there is no FPGA and XRT installed
  2. Reinstall Docker completely on your complete machine
    • back up any Docker images, if you need to preserve them
    • uninstall Docker - sudo apt-get remove docker docker.io docker-cli containerd containerd.io docker-engine runc
    • Remove all local docker files - sudo rm -Rf /var/lib/docker
    • Reinstall docker again
hanxue commented 3 years ago

I did some googling and and notice this issue is quite common if Docker is installed via snap.

How did you install Docker?

This should fix the snap installation

snap remove docker

Then follow the official instructions for installing Docker https://docs.docker.com/engine/install/ubuntu/

nevilshah235 commented 3 years ago

Thanks @hanxue. The issue was with the docker installation, once I reinstalled docker, it worked out fine.
