Message type "Experiment" has no field named "visualizer"

Please provide the following information when requesting support.

• Hardware (x86 PC with 1080Ti)
• Network Type: Mask_rcnn
• TLT Version: Not installed
• Training spec file
maskrcnn_train_resnet50.txt (2.1 KB)

• How to reproduce the issue ?

!tao model mask_rcnn train -e $SPECS_DIR/maskrcnn_train_resnet50.txt \
                     -d $USER_EXPERIMENT_DIR/experiment_dir_unpruned\
                     --gpus $NUM_GPUS


When I try to use TAO Toolkit 5.3.0 to train mask_rcnn on my own data from within a Jupyter notebook, I get the following error:

[INFO] Starting MaskRCNN evaluation.
[INFO] Loading specification from /workspace/tao-experiments/mask_rcnn/specs/maskrcnn_train_resnet50.txt

Any idea where I’m going wrong?

That worked! Thanks!
