I am using VisualDL 1.3.0 now. I mainly use the following functions:

• LogWriter.mode. such as with logwriter.mode("train") as writer
• Define before record. such as:

  loss_scalar = writer.scalar("loss")
  loss_scalar.add_record(step, cur_loss)

• histogram. such as:

  histogram1 = writer.histogram("Relation-BiLinear-W", 100)
  histogram1.add_record(step, relation_BL_w_value.flatten())

They all work well in VisualDL 1.3.0.

But, when I update it to 2.0.0b4, I found some errors respectively:

• AttributeError: 'LogWriter' object has no attribute 'mode'
• You don't need to define before recording. Just writer.add_scalar()
• There are only three ways to visualize.
