Yolov5 custom object detection model not loading - opencv

I have a trained a custom object detection model using yolov5 for 4 classes. I have downloaded the best.pt file. I am still confused about how to load this model using pytorch.
I tried running the following code to load the model as per Yolov5 official documentation
model = torch.hub.load('ultralytics/yolov5', 'custom', path='best.pt')
but when I tried printing model.names, I am not getting my custom class names. Is there anything I am missing?
Thank you!

Try clearing your cache by adding this: force_reload=True
Store your model in a local folder called model (in case you are locally
trying to run this)
then try adding this:
model = torch.hub.load('ultralytics/yolov5', 'custom', path='model/best-m.pt', force_reload=True)

How can we save darts model lets say TFT Model using mlflow

I want to save my Darts TFT MODEL using mlflow and load it using mlflow. Currently i log my model using sklearn flavor not i am unable to load it.
ERROR - (AttributeError: 'Trainer' object has no attribute '_accelerator_connector')
Currently i log my model using sklearn flavor not i am unable to load it.
When i tried to load model using mlflow.sklearn.load_model() it is giving error
ERROR - (AttributeError: 'Trainer' object has no attribute '_accelerator_connector')
Any help will be really appreciated.
Thanks

Running Ptr-Net on MXNet

We have a Ptr-Net model that we want to run. Can the MXNet be useful for this scenario. If not, what are the other libraries that we can use to run Ptr-Net models?
We are building a Ptr-Net model using TensorFlow as of now.
Currently we don't have a complete model for Ptr-Net, but you can define symbolic model for Ptr-Net. Here is a complete example for creating char-level lstm model: http://mxnet.io/tutorials/python/char_lstm.html

How to append an image to a rails object dynamically

How can I append an image to a model object in rails? For example, if I had a post, how could I upload/append an image to the object so that I can call it in the view dynamically? I know that the association would be a has_one relationship... Ive looked around and just can't find anything on this topic. Thanks.
The most common solution for model attachments in Rails is the Paperclip gem. Try using it, or take a look at a corresponding Ruby Toolbox category.

Paperclip namespace conflict

I have rather weird problem with paperclip gem. You know it defines Attachment class inside itself. So the model with exactly the same name already exists in my project. As the result in some parts of the code i cant get access to my previous Attachment model.
I tried to write full name of my model class, but the result was very interesting (in console):
ActiveRecord::Base::Attachment
=> Paperclip::Attachment
I can get access to my Attachment model inside AttachmentController and by default it console but nowhere else.
Also i tried to create simple object from console without attached file.
a.errors.sort
[]
a.save
TypeError: can't dump anonymous class Class
As you see object a has no errors but throws error in save.
Finally my aim is to copy a collection of Attachment objects from one holder-object to another. I mean deep copy, so files should be copied too. If you have any suggestions about these points I'll appreciate.
You can always access your class via "::Attachment", but make sure you're using the latest version of Paperclip. There were some namespace collision bugs that were fixed.

Rails: Image Upload with Tableless Model

Here is the scenario, i would like the user to input all the data and all and use em to populate a result. I won't need to store them in a database since i will just be showing them a result page.
I did http://railscasts.com/episodes/219-active-model and made my model tableless.
But now i have a problem when i wanna receive image upload from the user. I would also like to display that picture in the result page, and since i will just be using it once, if possible i wouldnt wanna store it in the database as well.
I tried implementing paperclip with the tableless model (since i couldnt find any other solution) but it seems that the model has inherit ActiveRecord::Base for it to work...
Is this possible? Or is this other way i can implement this?
Thanks!
If you were to succeed with using Paperclip for this, how would you get rid of the uploaded image once you no longer needed it? Without a database or some other form of persistent storage, how would you know where the image had been stored?
I think that you have some conceptual issues here that you should rethink before you start hacking up tableless models that accept image uploads.
But, if for some reason you really want to do it this way, then I would suggest just uploading the image without the benefit of a gem like Paperclip, which is really intended to make it easier to associate files with ActiveRecord objects. Just google for how you upload a file in Ruby, it's not really all that difficult.
OK, so you want to receive an image, and then display it right back, and not store the image. Can do.
What about a Controller that receives a file using multipart, and then transmits the file back to the request?
Controller file:
def upload
# Save file
name = params['datafile'].original_filename
directory = "tmp/uploads"
temp_file_name = File.join(directory, name)
send_file temp_file_name, :status=>200
end
You'll then just cleanup tmp when you need. Or, try out doing a File.delete temp_file_name when you need to.
If you want to validate that it's an image, you can do Paperclip model validation.
