Django中，调用GeoLite2-City.mmdb报错

Question

def index( request ):
    ip()
    return render(request, 'MyWeather_Templates/index.html')

def ip():
    headers = {}
    headers[
        'User-Agent'] = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36"
    response = requests.get('http://www.baidu.com/s?wd=ip', headers=headers)
    html = response.text
    reGET = re.compile('fk="(.*?)"').findall(html)
    for i in reGET:
        break
    ip = i
    reader = geoip2.database.Reader('./media/GeoLite2-City.mmdb')
    data = reader.city(ip)
    city =  data.city.names['zh-CN']
    print("IP Address: ", ip)
    print("国家: ", data.country.names['zh-CN'])  # names['zh-CN']转换为中文
    print("省份: ", data.subdivisions.most_specific.names['zh-CN'])
    print("城市: ", data.city.names['zh-CN'])
    print("纬度: ", data.location.latitude)  # 位置
    print("经度: ", data.location.longitude)
    print("时区：",data.location.time_zone)

报错信息：No such file or directory: './GeoLite2-City.mmdb'
我尝试将GeoLite2-City.mmdb放到media外面直接访问，但还是报这个错...这是为啥？
（PS：换成绝对路径就能访问到）
