我在群文件里面看到有两个框架做布匹检测问题，tensorflow和pytorch
里面代码有一些看不懂，也不太清楚什么是baseline？什么样的提交的结果叫很好？

def RMSE(y_true, y_pred):
return tf.sqrt(tf.reduce_mean(tf.square(y_true - y_pred)))
def build_model():
inp = Input(shape=(12,24,72,4)) #这里不懂是输入了一个什么样的四维的数据？
x_4 = Dense(1, activation='relu')(inp)
x_3 = Dense(1, activation='relu')(tf.reshape(x_4,[-1,12,24,72]))
x_2 = Dense(1, activation='relu')(tf.reshape(x_3,[-1,12,24]))
x_1 = Dense(1, activation='relu')(tf.reshape(x_2,[-1,12]))
x = Dense(64, activation='relu')(x_1) #这里全链接层后面1，64代表什么？
x = Dropout(0.25)(x)
x = Dense(32, activation='relu')(x)
x = Dropout(0.25)(x) #这里群里面问了代表丢弃的概率
output = Dense(24, activation='linear')(x)
model = Model(inputs=inp, outputs=output)
adam = tf.optimizers.Adam(lr=1e-3,beta_1=0.99,beta_2 = 0.99)
model.compile(optimizer=adam, loss=RMSE)
return model
model = build_model()
model.load_weights(’./user_data/model_data/model_mlp_baseline.h5’)
model.load_weights(’./model_mlp_baseline.h5’) #这里不懂是个什么权重？文件h5不知道代表什么？
test_path = ‘./tcdata/enso_round1_test_20210201/’
test_path = ‘./anno_train.json’ #这里上下两个路径为什么不同？
1. 测试数据读取
files = os.listdir(test_path)
files = os.listdir(dict(test_path))
test_feas_dict = {}
for file in files:
test_feas_dict[file] = np.load(test_path + file)
2. 结果预测
test_predicts_dict = {}
for file_name,val in test_feas_dict.items():
test_predicts_dict[file_name] = model.predict(val).reshape(-1,)
test_predicts_dict[file_name] = model.predict(val.reshape([-1,12])[0,:])
3.存储预测结果
for file_name,val in test_predicts_dict.items():
np.save(’./result/’ + file_name,val)
#打包目录为zip文件（未压缩）
def make_zip(source_dir=’./result/’, output_filename = ‘result.zip’):
zipf = zipfile.ZipFile(output_filename, ‘w’)
pre_len = len(os.path.dirname(source_dir))
source_dirs = os.walk(source_dir)
print(source_dirs)
for parent, dirnames, filenames in source_dirs:
print(parent, dirnames)
for filename in filenames:
if ‘.npy’ not in filename:
continue
pathfile = os.path.join(parent, filename)
arcname = pathfile[pre_len:].strip(os.path.sep) #相对路径
zipf.write(pathfile, arcname)
zipf.close()
make_zip()
程序没有跑通
