Known Issues
-
The video loader operator requires that the key frames occur, at a minimum,
every 10 to 15 frames of the video stream.
If the key frames occur at a frequency that is less than 10-15 frames, the
returned frames might be out of sync.
-
The DALI TensorFlow plugin might not be compatible with
TensorFlow versions 1.15.0 and later.
To use DALI with the TensorFlow version that does not have a
prebuilt plugin binary that is shipped with DALI, make sure
that the compiler that is used to build TensorFlow exists on the system
during the plugin installation. (Depending on the particular version, you
can use GCC 4.8.4, GCC 4.8.5, or GCC 5.4.)
-
Due to some known issues with meltdown/spectra mitigations and
DALI,
DALI shows the best performance when
running in Docker with escalated privileges, for example:
- privileged=yes in Extra Settings for AWS data
points
- --privileged or --security-opt
seccomp=unconfined for bare Docker
