How to get the HISTOGRAM and CONFUSION_MATRIX in TENSORBOARD parameters

Set parameters according to the VISUALIZATION_TOOLS.md file but could not get the result
```
TENSORBOARD:
ENABLE: True
LOG_DIR: # Leave empty to use cfg.OUTPUT_DIR/runs-{cfg.TRAIN.DATASET} as path.
CLASS_NAMES_PATH: # Path to json file providing class_name - id mapping.
CONFUSION_MATRIX:
ENABLE: True
SUBSET_PATH: # Path to txt file contains class names separated by newline characters.
# Only classes in this file will be visualized in the confusion matrix.
HISTOGRAM:
ENABLE: True
TOP_K: 10 # Top-k most frequently predicted classes for each class in the dataset.
SUBSET_PATH: # Path to txt file contains class names separated by newline characters.
# Only classes in this file will be visualized with histograms.
