When I work through Colab, when I continue experimenting, I get gaps in the graphs.
For example, the first time I run, I create a task and run a loop:
for i in range(1,100): clearml.Logger.current_logger().report_scalar("test", "loss", iteration=i, value=i)

Then, on the second run, I continue the task via continue_last_task and reuse_last_task_id and write task.set_initial_iteration(0). Then I start the cycle:
for i in range(100,200):
clearml.Logger.current_logger().report_scalar("test", "loss", iteration=i, value=i)
And then on the graphs I get a gap.
