Numpy not recognizing a proper dtype



My code is below:


import numpy as np
from nltk.tokenize import TweetTokenizer
from nltk import pos_tag

class tag_tokenizer:

tokenizer = TweetTokenizer() #learn tokenizing stuff
dt = np.dtype([("token", 'U16') , ("pos_tag","U5")])

def __init__(self, rawDocs):
self.tagged_data = np.array([pos_tag(self.tokenizer.tokenize(rawDoc)) for rawDoc in rawDocs], dtype=self.dt)



But I get the error:


TypeError: a bytes-like object is required, not 'list'



whenevery I try to initialize an instance of tag_tokenizer. My list is a lst of tuples of both string characters so I don't know why numpy wont let me. Do I have to create the array first, and then set the dtype, or am I just doing it wrong?

Regex - How to capture all iterations of a repeating pattern?

Image
Clash Royale CLAN TAG #URR8PPP Regex - How to capture all iterations of a repeating pattern? Take a look at this example, I want to capture not just the last iteration (which is 5), but also 2, 3 and 4. It says here: A repeated capturing group will only capture the last iteration. Put a capturing group around the repeated group to capture all iterations... but I don't know how to do this. Since I need this in C++, I was looking for a way to get all iterations of capturing group using some regex functions in C++, but I always end up with same groups which the website finds. How about instruction d((,d)*) ? (IMHO, this is meant in the cited text.) Though, this leaves still the task to separate the inner matches... – Scheff 17 mins ago instruction d((,d)*) Thou...
