这个问题会让我发疯：我有一个使用tflearn的卷积网络代码。我想保存我的模型并加载它以对不同的图像进行预测。我是这样做的：
def predictValues(image_path):
...
model = tflearn.DNN(convnet)
if not os.path.exists("emotionPrediction.tfl.meta"):
X = images.reshape(-1, 1, 268, 1)
Y = lables.reshape(-1, 7)
model.fit({'input': X}, {'targets': Y}, n_epoch=2, snapshot_step=500, show_metric=True)
model.save("emotionPrediction.tfl")
model.load(".\\emotionPrediction.tfl", weights_only=True)
print("Emotion values for %s: ", file):
....
images = [path1, path2, path3]
for x in images:
predictValues(x)
不幸的是，无论我如何改变路径，代码都无法工作。我得到了第一张图片的预测，但之后对于其他图片我得到了这个错误：

有人可以帮忙吗？我已经谷歌搜索了几个小时来解决这个问题但是徒劳无功..
你必须使用
model.predict(input)
qazxsw poi只会加载预先保存的模型文件。它不会立即给你预测。
