ValueError: Sample larger than population or is negative

Dear @vanhoanglepsa

When I am running python3 fewshot_sampling.py, It gives an error on Hadoop log.

HDFS
{'log_file': 'HDFS/HDFS_2k.log', 'log_format': '<Date> <Time> <Pid> <Level> <Component>: <Content>'}
Hadoop
{'log_file': 'Hadoop/Hadoop_2k.log', 'log_format': '<SessionId> <Date> <Time> <Level> \\[<Process>\\] <Component>: <Content>'}
Traceback (most recent call last):
  File "fewshot_sampling.py", line 48, in <module>
    samples_ids = adaptive_random_sampling(shuffle(content), shot)

Hi @khawar-islam

The error is caused by some modifications we made for other experimental settings. We've updated a version to fix this issue. Please find the new sampling code here. Please update to the latest version to fix this issue.

@vanhoanglepsa Hello and thank you for your great work, would you please tell me how I can run fewshot sampling.py on my own raw log file
