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

****The Docks ps***

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.

How to fix the problem ?

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,

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

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

> 2、Cannot Access Stratum_Switch BfRt Python CLI Through bfshell

Access through the shell is very limited, see the limitations described here: https://github.com/stratum/stratum/blob/main/stratum/hal/bin/barefoot/README.run.md#access-bf-shell-via-telnet-experimental
