Thank you for the input, I am pretty new docker so that might be the problem, I haven’t created it in a docker file locally, so I will try that.

Hi Daniel.R.Armstrong
I also learned Docker recently and followed a lot of poor tutorials.
In this tutorial you will learn all the fundamentals you need to get your app working. https://training.play-with-docker.com/beginner-linux/#Task_0
This tutorial was a life saver for me and you can practice in their virtual session.
docker container logs your_container_name
This command is really helpful as it shows you the output of what your container/app is doing (console output).

Hi, I have exactly the same problem. How did you solve it?. Many thanks!
Hi diegobodner hope all is well!
Have you searched this thread for “pip list”. Having bulit more than 50 model apps many of the apps issues have been resolved using this command to amend the requirements.txt in the deployed model.
cheers mrfabulous1
Hi mrfabulous1, it works well now, I changed the pythorch and fastai version in the requirements.txt based on notebook versions.
It doen’t work the model, always predict the dogs and cats (and other stuff) as a Boxer…but it is another problem. if you have ever heard this same problem please let me know.
Many thanks.
Best regards!

Hi diegobodner I am glad to hear your model is now working.
There is probably a better thread than this one for discussing your issue.
I haven’t seen your particular issue before. However I am assuming your model is supposed to predict cats and dogs if this is the case then I would go to the section of the notebook below and check the confusion matrix.
I would check my directories container images of the correct class.
Also muellerzr has an image cleaner that you could try if that is an issue.
Not sure what you mean by
other stuff
But if you mean it predicts images of other things as a boxer even if they are not cats and dogs,
then this is another feature of the classifier which people are trying to find a solution to.
See this thread here. Handle data that belongs to classes not seen in training or testing
Have a jolly day mrfabulous1

Hi sri9 hope all is well!
In the first instance if you have not done so, I suggest you search this thread for posts relating to “pip list” and update the requirements.txt in the bear classifier to match the library versions of the platform you trained your model on.
I am assuming your bear model (pkl file) works in the notebook you created it in.
Hope this helps mrfabulous1

Hi arturola hope all is well!
If you haven’t done so already, can I suggest you search this thread for posts relating to “pip list” and update the requirements.txt file in the your classifier to match the library versions of the platform you trained your model on.
This is absolutely essential for your model to work,
I am assuming your bear model (pkl file) works in the notebook you created it in.
Hope this helps mrfabulous1
Hi mrfabulous1,
Thank you very much for your answer, that helped! Im using Colab as plattform and I pip listed the packages and updated the requirements.txt file.
Now I get the following error:

Is there something I can do or should I try with a different platform rather than using Colab?
Hi arturola
Colab is not the issue, when you deploy your model on render you are no longer using Colab.
The error message you are getting are normally related to the website at the other end refusing your requests.
please cut and paste your requirements.txt from your render repository here and the corresponding lines from your Colab notebook.
ps I also use Colab.

Hi arturola hope you are having a good day.
Can you comment out the https://download.pytorch.org/whl/cpu/torch-1.3.1-cp37-cp37m-linux_x86_64.whl line and add the line torch==1.3.1 to see if this helps.

Great! That worked!

Hi arturola hope you had a wonderful day today!
- Can you upload your server.py file please?
- Where is your .pkl file located?
- How long ago was your model file (.pkl) created?
- What is the size of your .pkl file?
- if your .pkl file is online you should be able to access it by pasting the link in your browser. You can also use
wget “your .pkl file web address”

I was able to get through to the link generation portion of the deployment tutorial, but I can’t figure out the customize app section. Where is the server.py and the app directory and how do I edit it?
