How to draw precision and recall curve for Known class?

[JiuqingDong]

Dear author, I would like to know how to draw the P-R curve and Confusion metrics for known classes.

Although you provide a function here, I can not use it to draw a PR curve for all classes.

OWOD/detectron2/evaluation/pascal_voc_evaluation.py

def plot_pr_curve(precision, recall, filename, base_path='/home/fk1/workspace/OWOD/output/plots/'):

def plot_pr_curve(precision, recall, filename, base_path='xxxxx/output/plots/'):
fig, ax = plt.subplots()
ax.step(recall, precision, color='r', alpha=0.99, where='post')
ax.fill_between(recall, precision, alpha=0.2, color='b', step='post')
plt.xlabel('Recall')
plt.ylabel('Precision')
plt.ylim([0.0, 1.05])
plt.xlim([0.0, 1.0])
plt.savefig(base_path + filename)
