Would you like to ask why the training result is nan

[yyyyet]

No code changes have been made, and the version of the library is compliant This is the result of my training Only the first picture was correct when the 10 pictures were tested Thanks to reassure!

Hi, I tested the code again but wasn't able to reproduce this issue. Are all the package requirements satisfied?

[yyyyet]

It is installed according to the Requirements you provided. I used to have a computer that could run the program successfully, but now I have changed to a new computer and it can't work. Is it because the 3070 can't use cuda10.0, but there is no error and warning in the running process. It is now successful only when testing with a single image for example: python main.py test -d salicon-p salicon.jpg These are all the libraries I use:

[alexanderkroner]

Indeed, the package versions are the same as the ones I tested the code with. Could it be that this issue is relevant for you?

[yyyyet]

Well, I don't know. I'll try again. Thank you.

I had the same problem with RTX4090 and this helps a lot!

Hi there! I'm having a similar issue with the the training result being NaN and only the first picture generating a result. I'm currently using a Windows computer, and I believe Nvidia-TensorFlow is for Linux machines. Do you have any suggestions for this? Thank you so much!

same nan. using cpu with the same speed with gpu.

[achilatiao]

same nun problem. Just delete the model you trained first. And It will be solve.

What do you mean by deleting the model I trained first?

[achilatiao]

nan nan nan nan nan nan nan nan nan nan nan nan nan 1.415068 1.325778 1.373514 nan

[achilatiao]

seams like still bugs

[achilatiao]

I use only 100 pictures in this three:1.415068 1.325778 1.373514 others used 10000 and it return nan

Then I delete all the .result and weight and start the traning again and here is the output:
