以下為出錯code：

import numpy as np
import cv2
import os
import pandas as pd
from six.moves import cPickle

# training data direction
train_dir = 'C:/Program Files/BACNN/trainingdataset'

X_train = []
y_age = []
y_gender = []

df = pd.read_csv('C:/Program Files/BACNN/trainingdataset/boneagetrainingdataset.csv')
a = df.values
m = a.shape[0]

path = train_dir
k = 0
print('Loading data set...')
for i in os.listdir(path):
    y_age.append(df.boneage[df.id == int(i[:-4])].tolist()[0])
    a = df.male[df.id == int(i[:-4])].tolist()[0]
    if a:
        y_gender.append(1)
    else:
        y_gender.append(0)
    img_path = path + i
    img = cv2.imread(path)
    print(img_path)
    img_G = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
    img_RE = cv2.resize(img_G, (300, 300))
    x = np.asarray(img_RE, dtype=np.uint8)
    X_train.append(x)

print('100% completed loading data')

# Save data
train_pkl = open('data.pkl', 'wb')
cPickle.dump(X_train, train_pkl, protocol=cPickle.HIGHEST_PROTOCOL)
train_pkl.close()

train_age_pkl = open('data_age.pkl', 'wb')
cPickle.dump(y_age, train_age_pkl, protocol=cPickle.HIGHEST_PROTOCOL)
train_age_pkl.close()

train_gender_pkl = open('data_gender.pkl', 'wb')
cPickle.dump(y_gender, train_gender_pkl, protocol=cPickle.HIGHEST_PROTOCOL)
train_gender_pkl.close()

不太了解為什麼會抓不到檔案位置，想尋求大家有什麼想法。
