Hi all,

I have 2 question:

1、How to run Stratum natively on the host (not in Docker containers)?


2、Cannot Access Stratum_Switch BfRt Python CLI Through bfshell

***run tofino-modle***

docker run --rm -it --privileged -v /usr/lib:/usr/lib  --network=host   stratumproject/tofino-model:latest-9.7.0

****run stratum *****
PLATFORM=barefoot-tofino-model ./start-stratum-container.sh   -bf_switchd_background=false   -enable_onlp=false -experimental_enable_p4runtime_translation  -incompatible_enable_bfrt_legacy_bytestring_responses

bfshell>
bfshell> bfrt_python
bfrt_cli_cmd:203 could not initialize bf_rt for the cli. err: 1
bfshell>

will encounter the error above "bfrt_cli_cmd:203 could not initialize bf_rt for the cli. err: 1",
Also, a prompt will appear at the stratum switch as following:


bf-sde> Python path configuration:
  PYTHONHOME = '/usr/'
  PYTHONPATH = (not set)
  program name = 'python3'
  isolated = 0
  environment = 1
  user site = 1
  import site = 1
  sys._base_executable = ''
  sys.base_prefix = '/usr'
  sys.base_exec_prefix = '/usr'
  sys.executable = ''
  sys.prefix = '/usr'
  sys.exec_prefix = '/usr'
  sys.path = [
    '/usr/lib/python38.zip',
    '/usr/lib/python3.8',
    '/usr/lib/python3.8/lib-dynload',
  ]
ModuleNotFoundError: No module named 'bfrtcli'
Failed to load bfrtcli python library



Edit file start-stratum-container.sh ,And add the line to it .
-v /home/cxc/mysde/bf-sde-9.7.0/install/lib/python3.8:/usr/lib/python3.8

Now when lanunch the command bfrt_python, we get the new error on stratum switch:

ERROR:root:code for hash blake2b was not found.

Not sure what exactly is meant by "...natively on the host..." but perhaps the following thread may help. To summarize, stratum was packaged as a VM as opposed to a container:

Hi Chen,

You can try the Debian packages (.deb) we publish. Check the "Assets" section here: https://github.com/stratum/stratum/releases
