Can't import the tokenizer

when I tried to launch the code
```python
import tkseem as tk
import csv

# initialize the tokenizer
tokenizer = tk.WordTokenizer()
tokenizer.train('data.txt')
# open the csv file and read the text data
with open('../uploads/tweets-ar.csv', mode='r', encoding='utf-8') as csv_file:
csv_reader = csv.reader(csv_file)
for row in csv_reader:
text = row[0]
# tokenize the text using tkseem
tokens = tokenizer.tokenize(text)
print(tokens)
```
i got this error
```shell
File "pathtomycode\tokenize.py", line 5, in
tokenizer = tk.WordTokenizer()
AttributeError: partially initialized module 'tkseem' has no attribute 'WordTokenizer' (most likely due to a circular import)
```

Start by reproducing the import from the reported tokenize.py example and inspect how tkseem exposes WordTokenizer. Check the import path and package entry point first, then verify that the example can initialize the tokenizer, train on data.txt, and reach tokenization of the CSV input without the reported AttributeError.
