我试图用ezread https://de.mathworks.com/matlabcentral/fileexchange/11026-ezread读取csv文件，但出现以下问题：
使用textscan时出错 第二个输入必须是包含至少一个>说明符或文字字段的格式字符向量。
ezread错误（第66行） data = textscan（fid，format_str，'delimiter'，file_delim，'headerlines'，1）;
我按如下方式调用该函数：
tmpName = '/path/file.csv';
structRead = ezread(tmpName, 'r');
我用 isfile（）检查了 tmpName 是否正确，所以它是正确的路径。
我文件的前两行具有以下格式：
a,b,c,d
1,2,e,f
您知道问题可能在哪里吗？
答案 0 :(得分：0)
您应该使用import random
import json
encounters = {
"enemy" : {
1 : "zombie",
2 : "wolf",
3 : "wraith"
},
"chest" : {
1 : "chest",
2 : "weapons_chest",
},
"npc" : {
1 : "villager",
},
"furniture" : {
1 : "bed"
},
"nothing" : {
1 : ""
}
}
area = {
"spawner" : {
"spawn" : {
"name" : "Spawn",
"interact" : "",
"solved" : False,
"connects" : {
1 : "alleyway_1"
}
}
},
"alley" : {
"alleyway_1" : {
"name" : "Alleyway 1",
"interact" : "",
"solved" : False,
"connects" : {
1 : "spawn",
2 : "alleyway_2",
3 : "hall"
}
},
"alleyway_2" : {
"name" : "Alleyway 2",
"interact" : "",
"solved" : False,
"connects" : {
1 : "alleyway_1"
}
}
}
}
def random_encounters():
print("random encounters")
encounters_keys = ["enemy", "chest", "npc", "furniture", "nothing"]
weights_a = [0.3, 0.1, 0.05, 0.05, 0.5]
for q, w in area.items():
for a, s in area[q].items():
encounter_a = random.choices(encounters_keys, weights_a)[0]
encounter_b = random.choice(list(encounters[encounter_a].keys()))
area[q][a]["interact"] = encounters[encounter_a][encounter_b]
print(json.dumps(area, indent=2))
random_encounters()
而不是ezread。但是，它不会识别逗号importdata上的分隔符。因此，您需要添加额外的行：
,结果是：
tmpName = importdata('/path/file.csv');
structRead = split(a, ',')
