Hi Gregor. I ran into error trying to make prediction on Mackey-Glass time series.

y_pred = fis(X)

I ran a code from examples and got:

---------------------------------------------------------------------------

Cold you please help to solve that issue.

Hello Gregor, i got this error while i'm trying to predict the result using fis.model.predict(X)

Input to reshape is a tensor with 32 values, but the requested shape has 1
[[{{node myanfis/sumLayer/Reshape}}]] [Op:__inference_predict_function_154498]

May i know why? And what should i do regarding this matter? Thank you!

i have stock data and try to predict it with anfis, and I got problem in InvalidArgumentError: slice index 15 of dimension 0 out of bounds. [[{{node ruleLayer_2/strided_slice_15}}]] when fit the model, I have 900 row with 1 column for data training and 96 with 1 column in data test

Dear Gregor,

I hope this email finds you well, first of all, thank you so much for sharing your code on GitHub. I have a problem working with it. I have 3 inputs and 1 output, and it gives the below error:

`/usr/local/lib/python3.7/dist-packages/tensorflow/python/eager/execute.py in quick_execute(op_name, num_outputs, inputs, attrs, ctx, name)
53 ctx.ensure_initialized()
54 tensors = pywrap_tfe.TFE_Py_Execute(ctx._handle, device_name, op_name,
---> 55 inputs, attrs, num_outputs)
56 except core._NotOkStatusException as e:
57 if name is not None:

Incompatible shapes: [16,1] vs. [15,1]`

I found that 16 is my batch size and when I change it, this number changes.

(I found a solution and the solution is batch_size=1) which is SGD

Thank you in advance

Kind regards

Hamed

Hello,

I have a problem with the prediction section, would you please guide me. in the below code I have got the error.

y_pred = fis.model.predict(X_test)

Error:
InvalidArgumentError: Graph execution error:

Input to reshape is a tensor with 32 values, but the requested shape has 1
[[{{node myanfis/sumLayer/Reshape}}]] [Op:__inference_predict_function_68010]

Thank you in advance

Hello,

How to deal with multiple inputs using this anfis? I have 8 variables as the inputs to predict one output, but the run.py gives an error that is "This ANFIS implementation works with 2 to 6 inputs", so how to deal with this issue, please give some suggestions, thanks.

We can predict the data we have. So how do we predict for the future?

Hello,

I have a problem with the training section, would you please guide me. in the below code I have got the error.

y_pred = fis.model.fit(X_train, y_train,
epochs=param.n_epochs,
batch_size=param.batch_size,
validation_data=(X_test, y_test),
callbacks=[tensorboard_callback])

Error:
InvalidArgumentError: Graph execution error:

Node: 'myanfis/ruleLayer/Reshape_1'
Input to reshape is a tensor with 104 values, but the requested shape requires a multiple of 16
[[{{node myanfis/ruleLayer/Reshape_1}}]] [Op:__inference_train_function_2861]

Thank you in advance
