error in running dqn and ddqn about dqn

[ShanHaoYu]

just did the above mentioned :

from keras import backend as K
K.set_image_dim_ordering('th')

and it works for me :)

run into the same error with dqn.py, any idea? @Exception4U @tokb23

I think updating ur keras API should solve problem
pip install --upgrade keras

[zhongyaohui888]

As I upgraded, I still have the same error:
raise ValueError(err.message)
ValueError: Negative dimension size caused by subtracting 8 from 4 for 'conv2d_1/convolution' (op: 'Conv2D') with input shapes: [?,4,84,84], [8,8,84,32].

Ohhh !!! in that can you post your ~/.kerasrc file? ‌

I get that same error, even after I change my keras.json file to
{
"image_dim_ordering": "th",
"epsilon": 1e-07,
"floatx": "float32",
"backend": "tensorflow"

[Exception4U]

May be you refer here <https://stackoverflow.com/questions/41651628/negative-dimension-size-caused-by-subtracting-3-from-1-for-conv2d> and change function call ‌
