AttributeError: module 'google.cloud.vision_v1' has no attribute 'Feature' - python-3.x

Question

the title. I have copied the code as is from google's website but it is not working:
import io
from google.cloud import vision_v1
def sample_batch_annotate_files(file_path="path/to/your/document.pdf"):
"""Perform batch file annotation."""
client = vision_v1.ImageAnnotatorClient()
# Supported mime_type: application/pdf, image/tiff, image/gif
mime_type = "application/pdf"
with io.open(file_path, "rb") as f:
content = f.read()
input_config = {"mime_type": mime_type, "content": content}
features = [{"type_": vision_v1.Feature.Type.DOCUMENT_TEXT_DETECTION}]
# The service can process up to 5 pages per document file. Here we specify
# the first, second, and last page of the document to be processed.
pages = [1, 2, -1]
requests = [{"input_config": input_config, "features": features, "pages": pages}]
response = client.batch_annotate_files(requests=requests)
for image_response in response.responses[0].responses:
print(u"Full text: {}".format(image_response.full_text_annotation.text))
for page in image_response.full_text_annotation.pages:
for block in page.blocks:
print(u"\nBlock confidence: {}".format(block.confidence))
for par in block.paragraphs:
print(u"\tParagraph confidence: {}".format(par.confidence))
for word in par.words:
print(u"\t\tWord confidence: {}".format(word.confidence))
Yet it is not working and giving me the following error:
File "---", line 16, in sample_batch_annotate_files
features = [{"type_": vision_v1.Feature.Type.DOCUMENT_TEXT_DETECTION}]
AttributeError: module 'google.cloud.vision_v1' has no attribute 'Feature'
I am using a conda environment and this is the .yml - as I read in another posts, I have installed the Google-api-python-client and google-cloud-vision as recommended. Might it be related to the 'google-cloud-vision' version 1.0.1 when it should be 3.5.1 ? how to update it? I installed it with: conda install -c conda-forge google-cloud-vision

Answer 1

Manually installed google-cloud-vision downloading the tar.bz2 from Anaconda.
activate [env]
conda install path-to-tar
By doing that I had my google-cloud-vision package update to the version I chose, but then I had an issue with PROTO. The error said that could find the module "import proto".
What I did is to update: conda install -c conda-forge google-api-python-client
and that solved the issue.
