I am passing a list from flask function to another function, and getting this value error.
我正在将一个列表从 Flask 函数传递给另一个函数，并得到这个值错误。
My code at sending end:
我在发送端的代码：
@app.route('/process', methods=['POST'])
def process():
name = request.form['name']
comment = request.form['comment']
wickets = request.form['wickets']
ga = request.form['ga']
ppballs = request.form['ppballs']
overs = request.form['overs']
score = [name,comment,wickets,ga,ppballs,overs]
results = []
results = eval_score(score)
print results
Receiver end :
接收端：
def ml_model(data):
col = pd.DataFrame(data,columns=['runs','balls', 'wickets', 'ground_average', 'pp_balls_left', 'total_overs'])
predicted = predictor(col)

Please let me know where I am going wrong.

Simply change
简单地改变
col = pd.DataFrame(data, columns=['runs','balls', 'wickets', 'ground_average', 'pp_balls_left', 'total_overs'])
for
为了
col = pd.DataFrame([data], columns=['runs','balls', 'wickets', 'ground_average', 'pp_balls_left', 'total_overs'])
You want [data]for pandasto understand they're rows.
你想[data]为pandas了解他们的行。
Simple illustration:
简单说明：
a = [1, 2, 3]
>>> pd.DataFrame(a)
0
0 1
1 2
2 3
>>> pd.DataFrame([a])
0 1 2
0 1 2 3

I was having similar issues with making a dataframe from regressor coefficients (regressor.coeff_), and brackets gave another error asking for 2-d input. If you get this error, try appending the input array with [0] so it pulls the values out. ex: data[0]
我在从回归系数（regressor.coeff_）制作数据帧时遇到了类似的问题，括号给出了另一个要求二维输入的错误。如果您收到此错误，请尝试使用 [0] 附加输入数组，以便将值拉出。例如：数据[0]
