Keyerror : 0

[MalavikaAR]

I got an error while running the NumPy neural network code using my dataset,
"'DataFrame' object has no attribute 'reshape'".
Also then I ran using your dataset make_moons, and again I got an error
"Keyerror: 0".

ln [19]:
#Training
params_values = train(np.transpose(X_train), np.transpose(y_train.reshape((y_train.shape[0], 1))), NN_ARCHITECTURE, 10000, 0.01)[0]

KeyError Traceback (most recent call last)
in ()
1 # Training
----> 2 params_values = train(np.transpose(X_train), np.transpose(y_train.reshape((y_train.shape[0], 1))), NN_ARCHITECTURE, 10000, 0.01)[0]

KeyError: 0

Would you please help me with what to do?
Is it necessary to take the transpose and reshaping the X and y??

Hi @MalavikaAR 👋. ! Judging by the error I think that you are trying to pass pandas.DataFrame instead of numpy.array through the neural network.

[MalavikaAR]

Ohh, okay, I will try to change that in my dataset. But what was the issue in trying with make_moons??

Heyy @SkalskiP , I changed it to numpyarray, and that error was gone, thankyou, but now I got the following error:

---

KeyError Traceback (most recent call last)
in ()
1 # Training
----> 2 params_values = train(np.transpose(X_train), np.transpose(y_train), NN_ARCHITECTURE, 10000, 0.01)

1 frames
in update(params_values, grads_values, nn_architecture, learning_rate)
1 def update(params_values, grads_values, nn_architecture, learning_rate):
2 for layer_idx, layer in enumerate(nn_architecture):
----> 3 params_values["W" + str(layer_idx)] -= learning_rate * grads_values["dW" + str(layer_idx)]
4 params_values["b" + str(layer_idx)] -= learning_rate * grads_values["db" + str(layer_idx)]
5

KeyError: 'W0'

Would you please help me? I noticed some other people have asked about the same error in your article in the 'medium'.

@MalavikaAR could you please show me how did you use make_moons function?

Please take a look at this link. I have tried it in colab.

I just wanted to add, the error is gone when I deleted the last indexing [0] of ln: [19] and got an accuracy of 0.98.
But I am not sure if it is the right thing to do.
