I uploaded my first model yesterday and used the label assist tool without any issues. Today I tried uploading a new version of the model but it took significantly longer to load, and more importantly, the labeling assist tool doesn’t work. Upon first glance, when I click label assist, chose my model version and click “continue”, the gui just says “Loading model… this may take a few moments.”. 20 minutes of waiting later, I opened the chrome dev tools and found out that the GET request for the model 404ed with this error:  
Failed to load resource: the server responded with a status of 404  
There was a url listed under the link which displays this:  
{  
“error”: {  
“message”: “No trained model was found for this model version.”,  
“type”: “GraphMethodException”,  
“hint”: “You must train a model on this version with Roboflow Train before you can use inference.”,  
“e”: [  
{}  
]  
}  
}

I thought that maybe I had uploaded the model incorrectly, so I tried again, but it says this:  
loading Roboflow workspace…  
loading Roboflow project…  
An error occured when getting the model upload URL: This version already has a trained model. Please generate and train a new version in order to upload model to Roboflow.

It also appears in the versions tab of the app. So does it exist, or does it not??  
I’m not sure what’s causing this.

I’ve tried an additional 2 other models. The last 4 have had the same issue.
