我有一個txt文件,它有8列,我選擇1列爲我的特徵提取,它給了我13個特徵值,輸出數組的形狀將是[1x13]。 同樣我有一個文件夾中的5個txt文件我想運行一個循環,以便返回的變量將有5x13的數據。如何在張量流中增加多維數組?
def loadinfofromfile(directory,sd,channel):
# subdir selection and read file names in it for particular crack type.
subdir, filenames = loadfilenamesindirectory(directory,sd)
for i in range(5):
# join the directory sub directory and the filename
loadfile = os.path.join(directory,subdir,filenames[i])
# load the values of that paticular file into tensor
fileinfo = tf.constant(np.loadtxt(loadfile),tf.float32)
# select the particular column data (choosen from crack type, channel no)
fileinfo_trans = tf.transpose(fileinfo)
fileinfo_back = tf.gather(fileinfo_trans,channel)
# extracting features from selected column data gives [1x13]
pool = features.pooldata(fileinfo_back)
poolfinal = tf.concat_v2([tf.expand_dims(pool,0)],axis=0)
return poolfinal
在上面的函數,我能得到[1x13]將變量「池」和我期待的變量poolfinal的大小[5x13],但我把它作爲[1x13]。 如何在垂直方向進行連接? 我在循環中犯的錯誤是什麼?
當我使用pool.append我不用再在到poolfinal,我想複製這樣做使用tensorflow功能concat_v2 – Raady
