Which Mackey-Glass code are you trying to run? If it's the results from the original LMU paper, that code base is preserved here https://github.com/nengo/keras-lmu/blob/paper/experiments/mackey-glass.ipynb and should continue to run (note that you will need to be on the However, from a brief look at your code, it looks like the problem is here As you said
So the You can see the API of LMUCell here and an example of using the API in practice here. |

Thank you very much for replying sir, I read the paper and tried to run the
code from here
https://github.com/nengo/keras-lmu/blob/paper/experiments/mackey-glass.ipynb
in last month on Google colab it ran well without error and in recent
because of updated versions of lmu 0.2.0 and 0.3.0 it has given me error in
colab as I mentioned there and I tried to change code according to the
updated 0.3.0 version but I got some errors that I mentioned before.
Now, after your reply I ran the below code.
def make_lstm(units, layers):
model = Sequential()
model.add(LSTM(units,
input_shape=(train_X.shape[1], 1), # (timesteps, input_dims)
return_sequences=True)) # continuously outputs per timestep
for _ in range(layers-1):
model.add(LSTM(units, return_sequences=True))
model.add(Dense(train_X.shape[-1], activation='tanh'))
model.compile(loss="mse", optimizer="adam")
model.summary()
return model
def delay_layer(units, **kwargs):
return RNN(LMUCell(#units=units,
order=4,
memory_d=4,
#hidden_cell=tf.keras.layers.Layer,
#memory_d=memory_d,
hidden_cell=tf.keras.layers.SimpleRNNCell(units),
theta=4,
),
return_sequences=True,
**kwargs
def make_lmu(units, layers):
model = Sequential()
model.add(delay_layer(units,
input_shape=(train_X.shape[1], 1))) # (timesteps, input_dims)
for _ in range(layers-1):
model.add(delay_layer(units))
model.add(Dense(train_X.shape[-1], activation='linear'))
model.compile(loss="mse", optimizer="adam")
model.summary()
return model
def make_hybrid(units_lstm, units_lmu, layers):
assert layers == 4, "unsupported"
model = Sequential()
model.add(delay_layer(units=units_lmu,input_shape=(train_X.shape[1], 1)))
model.add(LSTM(units=units_lstm, return_sequences=True))
model.add(delay_layer(units=units_lmu))
model.add(LSTM(units=units_lstm, return_sequences=True))
model.add(Dense(train_X.shape[-1], activation='tanh'))
model.compile(loss="mse", optimizer="adam")
model.summary()
return model
layers = 4
lstm_model = make_lstm(units=25, layers=layers)
lmu_model = make_lmu(units=49, layers=layers)
hybrid_model = make_hybrid(units_lstm=25, units_lmu=40, layers=layers)
Still I am getting this error..

sir i.e updated code(of this

Thanks.

running with KerasLMU 0.3.0 I'd recommend coming by the forum
<https://forum.nengo.ai/> and we can help you there, it's just a better
format for these kinds of questions.
However, from a brief look at your code, it looks like the problem is here
LMUCell(units=units,
order=4,
memory_d=4,
hidden_cell=tf.keras.layers.Layer,
#memory_d=memory_d,
#hidden_cell=tf.keras.layers.SimpleRNNCell(212),
theta=4,
),
As you said
0.2.0 removed the units and hidden_activation parameters of LMUCell (these
are now specified directly in the hidden_cell.
So the units should be specified in the hidden cell, like
LMUCell(order=4,
memory_d=4,
hidden_cell=tf.keras.layers.SimpleRNNCell(units=212),
theta=4,
),
You can see the API of LMUCell here
<https://www.nengo.ai/keras-lmu/api-reference.html#keras_lmu.LMUCell> and
an example of using the API in practice here
<https://www.nengo.ai/keras-lmu/examples/psMNIST.html>.

It shouldn't make any difference whether you're running on Colab or not (it's just a Python environment in any case).

Sure sir, thank you very much for the help as you said I tried on colab(!pip
install git+https://github.com/nengo/keras-lmu@paper at the top of your
code. Or, if you wanted to install the 0.1.0 version (which I'm guessing is
what you were using before), you can install that by putting !pip install
lmu==0.1.0 at the top of your code) but it returned same only.
TypeError: __init__() missing 2 required positional arguments: 'memory_d'
and 'hidden_cell'
After that I changed it to this
RNN(LMUCell(
order=4,
memory_d=4,
hidden_cell=tf.keras.layers.SimpleRNNCell(units),
theta=4,
),
It ran with few warnings but could not produce results as said in the paper.

here lstm performance than lmu and hybrid I think this is because some
version differences or mistakes in codes as per new versions only, I want
to run this mackey-glass time series prediction to see lmu is best than
lstm and apply this to my problem, but due to version changes I am
strugglinh a lot to implement and proceed furthur that's why I asked you to
send me the updated mackey-glass codes where below part of code is changed
as per 0.3.0:

It shouldn't make any difference whether you're running on Colab or not
(it's just a Python environment in any case).
If you just want to recreate the results from the paper (from
https://github.com/nengo/keras-lmu/blob/paper/experiments/mackey-glass.ipynb),
then as mentioned you should install the paper branch of the LMU repo.
You can do this in Colab by adding !pip install git+
***@***.*** at the top of your code. Or, if
you wanted to install the 0.1.0 version (which I'm guessing is what you
were using before), you can install that by putting !pip install
lmu==0.1.0 at the top of your code. In either case, you should then be
able to recreate the results from the paper.
If you're wanting to *update* the code from the paper to work with recent
KerasLMU versions, I'd recommend coming by the forum
<https://forum.nengo.ai/> and we can help you there (that's a better
format for those kinds of research support questions). I don't see any
errors in the output you posted, just looks like you're getting a few
warnings (which should be safe to ignore).

Thank you very much I did it the same way only now I didn't any warnings
and errors and I got results in this way(attached the screenshot) which are
some what differ than in the
https://github.com/nengo/keras-lmu/blob/paper/experiments/mackey-glass.ipynb
here. I am majorly looking forward your guidance when I apply
LMU(especially tuning parameters) to my problem to get best accuracy(or
less rmse) than lstm, that I will post on forum. Thanks again.

Here I passed the missing parameters..
Even after passing out the missing parameters giving another error with units, even I installed the latest keras-lmu but same problem I think because version 0.2.0 removed the units and hidden_activation parameters of LMUCell (these are now specified directly in the hidden_cell. (#22) So please provide the updated codes for mackey-glass prediction problem also. Thanks in advance
