I'm looking for a way to use numpy, scipy and pybrain in python. If I try to install those I get the error: Microsoft Visual C++ 10.0 is required (Unable to find vcvarsall.bat). I have installed...

I am using Python 2.7 and trying to get PyBrain to work. But I get this error even though scipy is installed - Traceback (most recent call last): File "<stdin>", line 1, in <module>...

I want to run some experiments on semi-supervised (constrained) clustering, in particular with background knowledge provided as instance level pairwise constraints (Must-Link or Cannot-Link constra...

I have recently started using pyBrain to conduct some machine learning research. I am interested in GAs as well as ANNs - however despit the fact that the pyBrain homepage lists GA as one of the fe...

I am trying to use PyBrain for some simple NN training. What I don't know how to do is to load the training data from a file. It is not explained in their website anywhere. I don't care about the f...

I installed PyBrain via PyCharm and when I try to compile I get the following error: Traceback (most recent call last): File "C:/Users/Marcus/PycharmProjects/ANN/ann.py", line 2, in <module&gt...

I have a neural network created using PyBrain and designed to forecast time series. I am using the sequential dataset function, and trying to use a sliding window of 5 previous values to predict ...

I want to create an artificial neural network (in PyBrain) that follows the following layout: However, I cannot find the proper way to achieve this. The only option that I see in the documentati...

I'm testing out pybrain following the basic classification tutorial here and a different take on it with some more realistic data here. However I receive this error when applying trndata._convertTo...

I have a question in mind which relates to the usage of pybrain to do regression of a time series. I plan to use the LSTM layer in pybrain to train and predict a time series. I found an example co...

I need to solve a regression problem with a feed forward network and I've been trying to use PyBrain to do it. Since there are no examples of regression on pybrain's reference, I tried to adapt it'...

I have the following code, from the PyBrain tutorial: from pybrain.datasets import SupervisedDataSet from pybrain.supervised.trainers import BackpropTrainer from pybrain.tools.shortcuts impo...

Problem I am trying to use 5 years of consecutive, historical data to forecast values for the following year. Data Structure My input data input_04_08 looks like this where the first column is ...

Following the PyBrain documentation, Building Networks with Modules and Connections, I'm building a neural network piecewise (in contrast to using the buildNetwork shortcut). I'm constructing a sim...

Is there a way to save and recover a trained Neural Network in PyBrain, so that I don't have to retrain it each time I run the script?

Based on PyBrain's tutorials I managed to knock together the following code: #!/usr/bin/env python2 # coding: utf-8 from pybrain.structure import FeedForwardNetwork, LinearLayer, SigmoidLayer, Ful...

How does one return original data scale after normalising input data for the neural net. Normalising was made with the standard deviation method. But the problem has already discussed, it belongs t...

I have some difficulty training a DBN using Pybrain. First I tried to do it the simple way: net = buildNetwork(*layerDims) I faced this problem: How to do supervised deepbelief training in PyBr...

I have a neural network n pybrain,with two inputs,a hidden layer and a output layer.I use the following to train: trainer = BackpropTrainer(net,ds) trainer.trainUntilConvergence() net is the neu...

Here is my problem: After I managed to install anaconda (having python 3.4), I apparently managed to install pybrain too. But when i use 'import pybrain' from anaconda or from the terminal too I g...

I follow the PyBrain tutorial Classification with Feed-Forward Neural Networks and want to build my own classifier. I do not understand how _convertToOneOfMany modifies outputs. Why would initia...

I have some working code which correctly loads data from a csv file into a PyBrain Dataset: def old_get_dataset(): reader = csv.reader(open('test.csv', 'rb')) header = reader.next() fields = ...

I'm trying to install pybrain on python 3.2. It says here: https://github.com/pybrain/pybrain/pull/85 that it should work. However it does not for me. I tried: $export PYTHONPATH=$PYTHONPATH:'/...

Can anyone give me a practicale example of a recurrent neural network in (pybrain) python in order to predict the next value of a sequence ? (I've read the pybrain documentation and there is no cle...

Description Given a dataset that has 10 sequences - a sequence corresponds to a day of stock value recordings - where each constitutes 50 sample recordings of stock values that are separated by 5 ...
