When installing Tabulo, I get below:

Installing collected packages: tabulo
  Attempting uninstall: tabulo
    Found existing installation: tabulo 0.2.4.dev0
    Uninstalling tabulo-0.2.4.dev0:
      Successfully uninstalled tabulo-0.2.4.dev0
  Running setup.py develop for tabulo
Successfully installed tabulo

After this, when running below from my CLI:

tabulo --help

I get below error:

-bash: tabulo: command not found

I am running Python on Mac OS X. What am I doing wrong?

I'm a complete newbie when it comes to data science, but this project would greatly help mine own, but sadly I cannot run it due to the TF versions and as far as I'm aware Apple doesn't support TF1.5. (I'm using an M1 Mac) Any help is greatly appreciated

Hello, I found a performance issue in the definition of _build, luminoth/models/ssd/proposal.py, tf.shape(all_anchors)[0] will be calculated repeatedly during program execution, resulting in reduced efficiency. I think it should be created before the loop.

The same issue exists in tf.cast(total_anchors, tf.float32).

Looking forward to your reply. Btw, I am very glad to create a PR to fix it if you are too busy.

Hi,
I have installed all the packages properly and I have been trying the following curl command from my MacBook terminal:

curl -X POST http://localhost:5000/api/fasterrcnn/predict/ -H 'Content-Type: application/x-www-form-urlencoded' -H 'Postman-Token: 70478bd2-e1e8-442f-b0bf-ea5ecf7bf4d8' -H 'cache-control: no-cache' -H 'content-type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW' -F "image=@/Users/rudra/Desktop/page_12.jpg"
But it keeps outputting an error saying: {"error":"Missing image"}

Can anyone please help me solve this? I also tried -F image=@/Users/rudra/Desktop/page_12.jpg but no success. I even tried converting the curl request into a python post type request, but the same error.

Thanks in advance.

Upon hitting the command "tabulo checkpoint list" I got the below response

I haven't got this checkpoint in the list' 6aac7a1e8a8e' though It is present in the luminoth/checkpoints folder.
I have tried hitting the command with another checkpoint it showed in the list -> server web --checkpoint aad6912e94d9
but it says Checkpoint not present locally and downloading... which is never downloaded.

Please help me with this.

#luminoth #checkpoints #tabulo

Thanks.

Great work. May I ask what training data you used for the pre-trained table detection model? Thanks!

can you please send me the config file that you have used to create the checkpoint 6aac7a1e8a8e ?

Hi ,

I have few questions on tabulo

1. i am unable to download the checkpoint which is trained on tables i am able to see a cooc dataset faster rcnn and ssd.

2. how does tabulo work? i mean i dont see any installation of tesseract how is the able to display the characters from a table image?

Regards
Sekar

Hi, Great work.! I am more interested on text extraction. Could you guide me which module is being used from the text extraction in the pipeline.

Thanks for your project.

An official docker image would be great to get started quickly.

Hi, please, tell me how can I change the recognition language to Russian?

After I installed tabulo and run git....,cd tabulo and pip install -e . I tried to run tabulo --help , I get an error saying failed to create process. Anyone knows what's going on?

Error: No such command "sever". when I try to run the Tabulo service using tabulo sever web --checkpoint 6aac7a1e8a8e after downloading and unzipping the pretrained models into the luminoth/utils/pretrained_models directory.

Hi, I'm trying to use the pre-trained model. I've downloaded the google drive folder and placed it in pretrained_models. When I run tabulo checkpoint list I do not see the local checkpoint.

Any idea what is going on?

I have tried tabulo predict on one of the pdf images from your sample's but it didn't generate anything, Below is the full message of the output.

i installed tabulo and when I tried to run tabulo --help , I get an error saying Failed to create process. Can someone help me solve it??

I followed the installation process until the following command :

tabulo checkpoint list

I get the following error after executing the command:

Error:
AttributeError: module 'tensorflow' has no attribute 'contrib'

I am guessing its because I am using Tensorflow 2.0 and models dont support it. Is there a quick work around to this ?

Is it normal that the command tabulo predict takes so much time to process (like 30 seconds by image)?

Hi, Great work.! I am more interested on text extraction. Could you guide me which module is being used from the text extraction in the pipeline.

Hi guys, past month Luminoth was archived. You have plans to migrate to another toolkit? The project is awesome.

While running the tabulo --help , I am encountering the following error.
There seem to be a conflict between the two libraries, where each library want some specific version of click. I have downloaded both versions of click, i.e. 6.7 and 7.1.2. but still encountering error.

I've downloaded a JPEG into the Tabulo directory (that I've cloned) and tried to run PostMan by importing the curl command onto PostMan

Value as '2_resized.jpg'

The error is

You should replace :

Open and read the image to predict.

with tf.gfile.Open(path, 'rb') as f:
    try:
        image = Image.open(f).convert('RGB')
    except (tf.errors.OutOfRangeError, OSError) as e:
        click.echo()
        click.echo('Error while processing {}: {}'.format(path, e))
        return

with tf.gfile.Open(path, 'rb') as f:
    try:
        image = Image.open(f).convert('RGB')
        img = np.asarray(image)
        img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

Hi I have installed the project and predict api is working but their is no documentation how i can call extract api can you help me with this,

Thanks in advance,
