ValueError: substring not found

Any Idea what is wrong here?

Traceback (most recent call last):
File "/home/nawab/Documents/Project/skills-ml/examples/SkillExtractionEvaluation.py", line 60, in
candidate_skills = candidate_skills_from_sample(sample, skill_extractor)

having the exact same error...

Let edit line number 262 in file algorithms/nlp/init.py :
line = line.replace(bullet_char, '') replaced by line = line.replace(bullet_char, '',1)
Then it should works.

I have exactly the same problem. @khieunguyen But I made the change that u mentioned above and didn't solve my problem!
Any other solution? I get this error when I run the following code:

candidate_skills = candidate_skills_from_sample(sample, skill_extractor)
