我一直在尝试使用以下Python函数加载Python pickle文件:
import os
import cPickle as pickle
def load_var(var_name):
fid = open(var_name + '.pkl', 'rb')
data = pickle.load(fid)
fid.close()
return data
但我一直遇到以下错误:
ImportError: No module named sysid_functions
它抱怨在pickle.py文件中调用了一个名为sysid的
这应该非常简单:我过去经常使用pickle。这次怎么了?
import pickle
with open('data/cifar-10-batches-py/data_batch_1','rb') as f:
dat = pickle.load(f)
AttributeError: 'function' object has no attribute 'load'
下面的操作也会失败(如果load被注释掉)
with open ('data/cifar-10-batches-py/small_batch'
我想知道是否有可能在不提供MyClass代码的情况下正确读取pickle文件。
import pickle
class MyClass:
def __init__(self, n):
self._n = n
def give_vec(self):
return [1 for _ in range(self._n)]
if __name__ == '__main__':
m = MyClass(30)
with open('test.pickle', 'wb') as p:
我正在尝试一个“开始使用泡菜”的脚本。我设法从一个文件中保存了一个pickle文件,并加载了它。但是当我在一个文件(本例中是main.py )中保存一个pickle文件并从另一个文件中加载它时,我得到了一个错误。我可能漏掉了一些小东西,但我搞不清楚是什么。
main.py
import pickle
class Node:
"""This class represents a node"""
def __init__(self, value = None):
self.val = value
def toString(s
我试图安装这个名为pyautogui的模块,但当我输入终端pip install pyautogui (以及py -m pip install pyautogui)时,我发现了以下内容:
File "c:\users\USER\appdata\local\programs\python\python39\lib\lib2to3\pgen2\grammar.py", line 95, in load
d = pickle.load(f)
AttributeError: module 'pickle' has no attribute 'load
我正在尝试解压缩一个文件,但是在运行以下代码时我得到了这个错误:
import pickle
import pandas as pd
import numpy
unpickled_df = pd.read_pickle("./ToyData.pickle")
unpickled_df
或
import pickle
# load : get the data from file
data = pickle.load(open('ToyData.pickle', "rb"))
错误输出:
AttributeError
我正在为库存系统编写Python脚本。它需要通过pickle存储一个对象列表(称为locations)。下面是我使用的代码:
try:
with open(".config/autosave.bin", "rb") as dataFile:
locations = pickle.load(dataFile)
except (FileNotFoundError, PermissionError):
dispHTML("p", contents="Error in load: Save file incorr
我已经使用joblib.dump保存了我的文件,它工作正常。现在我想使用joblib.load()访问我的.pkl文件,但得到以下错误:
File "/usr/local/lib/python2.7/dist-packages/sklearn/externals/joblib/numpy_pickle.py", line 425, in load
obj = unpickler.load()
File "/usr/lib/python2.7/pickle.py", line 858, in load
dispatch[key](self)
我有一个python脚本,它使用sklearn joblib加载持久模型并执行预测。当我以我的用户名运行脚本时,脚本运行得很好,当其他用户尝试运行相同的脚本时,他们得到错误消息"ImportError: No module named numpy_pickle“
我还将脚本复制到另一个用户的主目录,并从那里运行它,仍然出现相同的错误,我也从python shell运行它,但没有任何变化。下面是我在Python shell中运行的代码:
from sklearn.externals import joblib
joblib.load("model_filename.pkl"
我有自定义list和字典类,在Python3.7中,这些类不再起作用。
import pickle
class A(dict):
pass
class MyList(list):
def __init__(self, iterable=None, option=A):
self.option=option
if iterable:
for x in iterable:
self.append(x)
def append(self, obj):
if isin
我有一个带有自定义分析器的tfidf记号器,
def ngrams(text, n=3):
text = str(text)
text = text.lower()
text = ' '+ text +' '
ngrams = zip(*[text[i:] for i in range(n)])
return [''.join(ngram) for ngram in ngrams]
# fit and transform
vectorizer = TfidfVectorizer(min_df=1, a
我正在使用python3。首先,我在终端中使用random.choice,它可以工作。
Python 3.2.3 (default, Feb 27 2014, 21:31:18)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import random
>>> x = [1, 2, 3]
>>> random.choice(x)
同时使用:
with open("data_file.pickle", "rb") as pfile:
raw_data = pickle.load(pfile)
我知道错误:
AttributeError: Can't get attribute '_unpickle_block' on <module 'pandas._libs.internals' from '/opt/conda/lib/python3.8/site-packages/pandas/_libs/internals.cpy
(可以直接跳到下面的问题,跳过介绍。)
从用户定义的类中挑选Python对象有一个常见的困难:
# This is program dumper.py
import pickle
class C(object):
pass
with open('obj.pickle', 'wb') as f:
pickle.dump(C(), f)
实际上,尝试从另一个程序loader.py中获取对象
# This is program loader.py
with open('obj.pickle', 'rb') as f:
我无法加载使用sklearn.externals.joblib.dump或pickle.dump保存的自定义转换器的实例,因为当前python会话中缺少自定义转换器的原始定义。
假设在一个python会话中,我定义、创建并保存了一个自定义转换器,它也可以在同一个会话中加载:
from sklearn.base import TransformerMixin
from sklearn.base import BaseEstimator
from sklearn.externals import joblib
class CustomTransformer(BaseEstimator, Tran
在spyder上读取.pkl文件(python3.6.5)时,会出现以下错误:

当我试图通过一个docker容器中的joblib加载一个预先训练好的模型时,得到了以下错误。
