Hi! I have a problem to run your project. Do you know, what is the problem?

I have the same issue as well

[thierrydecae]

me too :-(

[SarfraazMsa]

pip install scikit-learn==0.15.2 ...it will work

[samar5yadav]

same problem

[ronair01]

@SarfraazMsa - Thanks a lot! That worked for me!

[SarfraazMsa]

great then @ronair01

I had issues unpickling the pickle files so I set encoding to latin1 when loading. However, this provided the following error:

Traceback (most recent call last): File "C:\Users\Elitebook\Desktop\ImageTextRecognition-master\ImageTextRecognition-master\main.py", line 29, in classified = user.classify_text(os.path.join(dir_file, 'linearsvc-hog-fulltrain36-90.pickle')) File "C:\Users\Elitebook\Desktop\ImageTextRecognition-master\ImageTextRecognition-master\userimageski.py", line 129, in classify_text which_text = model.predict(self.to_be_classified['flattened']) File "C:\Users\Elitebook\AppData\Local\Programs\Python\Python36-32\lib\site-packages\sklearn\pipeline.py", line 150, in predict return self.steps[-1][-1].predict(Xt) File "C:\Users\Elitebook\AppData\Local\Programs\Python\Python36-32\lib\site-packages\sklearn\linear_model\base.py", line 215, in predict scores = self.decision_function(X) File "C:\Users\Elitebook\AppData\Local\Programs\Python\Python36-32\lib\site-packages\sklearn\linear_model\base.py", line 196, in decision_function % (X.shape[1], n_features)) ValueError: X has 0 features per sample; expecting 3920

I assume this is because the code is unable to detect the objects as text since the "Objects Containing Text Detected" page is empty. Can anyone help me out here?

Hi guys, sorry but I have not been working on this project for years. The code base is really old and completely outdated. Not really sure how to help here.

[suhasdatascientist]

now that issue has been resolved by downgrading scikit learn to 0.15.1 version, but still the characters that recognized from the same image for the same code is different, where exaclty the problem will be

[rchavezj]

pip install scikit-learn==0.15.2 ...it will work

Since downgrading is the solution, I assume we need to change a certain syntax for the newest version of scikit-learn correct?

[SarfraazMsa]

yes

pip install scikit-learn==0.15.2 ...it will work

Since downgrading is the solution, I assume we need to change a certain syntax for the newest version of scikit-learn correct?

yes @rchavezj
