Pose Detection App - Number of Scales Error - CPU_ONLY

Running the pose detection example gives the following error:

Error:
Temporarily, the number of scales (`--scale_number`) cannot be greater than 1 for `CPU_ONLY` version.

Coming from:
- /opt/scanner-base/thirdparty/build/openpose/src/openpose/wrapper/wrapperAuxiliary.cpp:wrapperConfigureSecurityChecks():133
- /opt/scanner-base/thirdparty/build/openpose/src/openpose/wrapper/wrapperAuxiliary.cpp:wrapperConfigureSecurityChecks():152
- /opt/scanner-base/thirdparty/build/openpose/include/openpose/wrapper/wrapper.hpp:configure():941
terminate called after throwing an instance of 'std::runtime_error'

I tried changing pose_num_scales from 3 to 1:

frame = db.sources.FrameColumn()
poses_out = db.ops.OpenPose(
    frame=frame,
    pose_num_scales=1,      #3 
    pose_scale_gap=0.33,
    device=device)

This results in the following error:
