我正在嘗試一個簡單的來自github link的tensorflow演示代碼。
我目前使用Python版本3.5.2
TypeError:只能將整數標量數組轉換爲標量索引
Z:\downloads\tensorflow_demo-master\tensorflow_demo-master>py Python
3.5.2 (v3.5.2:4def2a2901a5, Jun 25 2016, 22:18:55) [MSC v.1900 64 bit (AMD64)] on win32<br> Type "help", "copyright", "credits" or "license" for more information.
我就遇到了這個錯誤,當我試着在命令行board.py。我已經安裝了運行所需的所有依賴項。
def _read32(bytestream):
dt = numpy.dtype(numpy.uint32).newbyteorder('>')
return numpy.frombuffer(bytestream.read(4), dtype=dt)
def extract_images(filename):
"""Extract the images into a 4D uint8 numpy array [index, y, x, depth]."""
print('Extracting', filename)
with gzip.open(filename) as bytestream:
magic = _read32(bytestream)
if magic != 2051:
raise ValueError(
'Invalid magic number %d in MNIST image file: %s' %
(magic, filename))
num_images = _read32(bytestream)
rows = _read32(bytestream)
cols = _read32(bytestream)
buf = bytestream.read(rows * cols * num_images)
data = numpy.frombuffer(buf, dtype=numpy.uint8)
data = data.reshape(num_images, rows, cols, 1)
return data

這對我有用,但後來得到這個錯誤:w_h = tf.histogram_summary(「權重」,W) AttributeError:模塊'tensorflow'沒有屬性'histogram_summary' –
在這裏有相同的問題。 – Amir
這是因爲api在最新版本中發生了變化。現在直方圖彙總已移至tf.summary.histogram。 – oat
