Pickle.load（）给出无效的加载密钥，＆＃x27; \ x9c＆＃x27;错误

我正在尝试pickle.load（）一个缓存二进制文件，但它一直在给出无效的密钥错误。

我的代码

import pickle
filename = r'C:\Users\user\Downloads\Project\cache\sample'
file = open(filename, "rb")
pickle_time = pickle.load(file)
print(pickle_time)

错误

get key 'filename.df' -> invalid load key, '\x9c'.

我尝试了腌制。加载其他一些在其他人的计算机上写的二进制文件，它效果很好，只有当我ccriple.load（）时，它才会丢弃此问题。二进制文件在我的系统上写入。

我使用烧瓶调查来写

from flask_caching import Cache

# app is a dash app
cache = Cache(
        config={
            'CACHE_TYPE': 'FileSystemCache',
            'CACHE_DIR': os.path.join(os.getenv('DASH_CACHE'), 'cache', 'my_data'),
            'CACHE_THRESHOLD': 0,
            'CACHE_DEFAULT_TIMEOUT': 24 * 60 * 60
        }
    )
    

cache.init_app(app.server)

u_id='0000'
ps='system0000'
session_id = u_id + '___' + ps + '___' +datetime.now().strftime('%Y%m%d_%H%M%S')

# RH is an internal class for reading data from DB and performing post processing
df = RH.GeneratePriceJSON(lat, lng, 15,currency=currency, no_limit=False)
df = json.dumps(df)

@app.callback(
[Output('some-value', 'children')],
[Input('some-url', 'search')],
)
def foo(some_url):
    with app.server.app_context():
        cache.set(session_id + '.' + 'df', df)
        df = session_id + '.' + 'df'
    return df

原文

I am trying to pickle.load() a cache binary file but it keeps on giving invalid key errors.

My code

import pickle
filename = r'C:\Users\user\Downloads\Project\cache\sample'
file = open(filename, "rb")
pickle_time = pickle.load(file)
print(pickle_time)

The error

get key 'filename.df' -> invalid load key, '\x9c'.

I tried pickle.load on some other binary files written on someone else's computer and it worked fine, it's only throwing this issue when I pickle.load() binary files writen on my system.

I write using flask-cache

from flask_caching import Cache

# app is a dash app
cache = Cache(
        config={
            'CACHE_TYPE': 'FileSystemCache',
            'CACHE_DIR': os.path.join(os.getenv('DASH_CACHE'), 'cache', 'my_data'),
            'CACHE_THRESHOLD': 0,
            'CACHE_DEFAULT_TIMEOUT': 24 * 60 * 60
        }
    )
    

cache.init_app(app.server)

u_id='0000'
ps='system0000'
session_id = u_id + '___' + ps + '___' +datetime.now().strftime('%Y%m%d_%H%M%S')

# RH is an internal class for reading data from DB and performing post processing
df = RH.GeneratePriceJSON(lat, lng, 15,currency=currency, no_limit=False)
df = json.dumps(df)

@app.callback(
[Output('some-value', 'children')],
[Input('some-url', 'search')],
)
def foo(some_url):
    with app.server.app_context():
        cache.set(session_id + '.' + 'df', df)
        df = session_id + '.' + 'df'
    return df
