[FIXED] ValueError: Cannot feed value of shape (100, 200, 66, 3) for Tensor Placeholder:0, which has shape (?, 66, 200, 3)

Issue

My development environment is windows and I encountered a error while executing my code. How can I fix this?

The result below is the output when running train.py.

Error generated while executing code:

ValueError: Cannot feed value of shape (100, 200, 66, 3) for Tensor Placeholder:0, which has shape (?, 66, 200, 3)

Solution

remove python 3.10.5 and After installing 3.6.8, I entered the following command and it worked fine.

python.exe -m pip install -U pip
python.exe -m pip install tensorflow==1.15.0 tensorboard==1.15.0 scipy==1.2.0 urllib3==1.13.1 Pillow opencv-python```
