RuntimeError: Loading operator with error:Load operator failed

[vig720]

Hello Everyone,
I am new to using Towhee, I am trying to run a basic code provided in their user guide

I am trying to run this code

`from towhee import ops, pipe, DataCollection

p = (
pipe.input('file_name')
.map('file_name', 'img', ops.image_decode.cv2())
.map('img', 'vec', ops.image_text_embedding.clip(model_name='clip_vit_base_patch32', modality='image'))
.map('vec', 'vec', ops.towhee.np_normalize())
.map(('vec', 'file_name'), (), ops.ann_insert.faiss_index('./faiss', 512))
.output()
)

for f_name in ['https://raw.githubusercontent.com/towhee-io/towhee/main/assets/dog1.png',
'https://raw.githubusercontent.com/towhee-io/towhee/main/assets/dog2.png',
'https://raw.githubusercontent.com/towhee-io/towhee/main/assets/dog3.png']:
p(f_name)

p.flush()

search image by text

decode = ops.image_decode.cv2('rgb')
p = (
pipe.input('text')
.map('text', 'vec', ops.image_text_embedding.clip(model_name='clip_vit_base_patch32', modality='text'))
.map('vec', 'vec', ops.towhee.np_normalize())
# faiss op result format: [[id, score, [file_name], ...]
.map('vec', 'row', ops.ann_search.faiss_index('./faiss', 3))
.map('row', 'images', lambda x: [decode(item[2][0]) for item in x])
.output('text', 'images')
)

DataCollection(p('a cat')).show()`

But I am getting this error

`RuntimeError Traceback (most recent call last)

Can some one let me know what is wrong
