Having issues with CCXT Example and Tensor Flow #171

Closed bugs181 closed 4 years ago

bugs181 commented 5 years ago

Also having issues with tensor flow here. Came from a CCXT example and this particular code:


Code:

const retrieveMACD = (klines) => {
  const closes = klines.map(kline => kline[4])
  var macdInput = {
    values: closes,
    fastPeriod: 12,
    slowPeriod: 26,
    signalPeriod: 9,
    SimpleMAOscillator: false,
    SimpleMASignal: false,
  }

  const macdResults = MACD.calculate(macdInput)
  return macdResults
}

Output:

Update: Switched from pnpm to npm and made no difference.

Tensorflow removed in 3.0. It should work now
