Error plus warning: CPU does not support avx2 instruction in the Watson install

  • 1.  Error plus warning: CPU does not support avx2 instruction in the Watson install

    Posted Thu October 22, 2020 07:57 PM

    We are running Cloud pak for Data 2.5 and during while installing Watson, we encounter this error:

    “WARNING: CPU does not support avx2 instruction set.

    Checking chrony / ntp / clockdiff

    ERROR: /usr/local/bin is not in environment variable PATH. Please add

    it and try again “

    Let us know how to resolve this.

    The warning error you indicated "WARNING: CPU does not support

    avx2

    instruction set."

    will appear if installing Watson assistant and AVX2 support is missing.

    See this documentation:

    https://www.ibm.com/support/knowledgecenter/SSQNUZ_2.5.0/cpd/svc/watson/assistant-install-142.html

    “The systems that host the service must meet these additional requirements:

    * Run on Intel architecture nodes

    only.

    * CPUs must have 2.4 GHz or higher

    clock speed.

    * CPUs must support Linux SSE

    4.2.

    * CPUs must support the AVX2 instruction set extension. (Most CPUs

    since 2013 support this extension). The service cannot function

    properly without AVX2 support.

    “

    Make sure these requirements are met prior to installing Watson

    assistant.
