Hello Team,

I developed one ML object detection model 2 years ago. Now I what to enhance this model with more training data sets. 2 years ago the process of model generation was pretty simple. We needed to click the "Train the Model" button but now it is integrated with Google Colab. So I am facing an error while generating the ML model. Please find the details.
Error :

1. In the "Start training" step.
   NotImplementedError: Cannot convert a symbolic Tensor (cond_2/strided_slice:0) to a numpy array.

2. In the Export inference graph step:
   FileNotFoundError: [Errno 2] No such file or directory: '/content/output' Because of previous step did not done successfully.

I tried the same process by creating a new model but got the same error for all the projects.

Please help me to resolve this issue
