Change configpath to absolute path
In Pycharm pip package, it prompts an error: module ‘pip’ has no attribute ‘main’
Reason: Because my pip 18.1 version does not have main()
Solution.
If you do not downgrade pip, go to the package_tool.py file in the helpers directory of Pycharm
Modify the functions do_install and do_uninstall as follows.
Use Python today. However, I met a mistake. A crazy stroke. Some say the path is wrong, others say it is… The information found on the Internet is also very few. Later, I suddenly found that the elements I can see temporarily on the page can be located and operated. What cannot be seen cannot be carried out… PS I didn’t join the full screen at this time
Seeing this, I suddenly thought whether it was caused by the nonfull screen of the page. OK. He really caused it. With the full-screen code, there will be no problem

When using numpy.load (‘xxx. NPY ‘) data, an error is reported
Unicode error: unpicking a python object failed: Unicode decodeerror
Due to the problem of default encoding, the data cannot be unpacked:
encoding must be 'ASCII', 'Latin1', or 'bytes'
therefore, when using NP. Load() , you need to add encoding options:
data = NP. Load ('mynpy. NPY', encoding = 'Latin1')
can be loaded successfully
If you use python3 to read the NPY generated by python2, coding errors may occur. It is explained in the source code of numpy:
# https://github.com/numpy/numpy/blob/v1.16.1/numpy/lib/npyio.py#L287-L453
# line 317
encoding : str, optional
What encoding to use when reading Python 2 strings. Only useful when
loading Python 2 generated pickled files in Python 3, which includes
npy/npz files containing object arrays. Values other than 'latin1',
'ASCII', and 'bytes' are not allowed, as they can corrupt numerical
data. Default: 'ASCII'
# Only one of the following three encoding methods is allowed
# line 390
if encoding not in ('ASCII', 'latin1', 'bytes'):
# The 'encoding' value for pickle also affects what encoding
# the serialized binary data of NumPy arrays is loaded
# in. Pickle does not pass on the encoding information to
# NumPy. The unpickling code in numpy.core.multiarray is
# written to assume that unicode data appearing where binary
# should be is in 'latin1'. 'bytes' is also safe, as is 'ASCII'.
#
# Other encoding values can corrupt binary data, and we
# purposefully disallow them. For the same reason, the errors=
# argument is not exposed, as values other than 'strict'
# result can similarly silently corrupt numerical data.
raise ValueError("encoding must be 'ASCII', 'latin1', or 'bytes'")

a required dependency when compiling Pillow from source.

I searched hard on the Internet and finally found the answer in stack overflow. It turned out that there was a lack of dependency package

FROM python:alpine RUN apk --update add libxml2-dev libxslt-dev libffi-dev gcc musl-dev libgcc openssl-dev curl RUN apk add jpeg-dev zlib-dev freetype-dev lcms2-dev openjpeg-dev tiff-dev tk-dev tcl-dev RUN pip install Pillow
So you can build successfully
Install these dependencies directly, and then you can install them directly in the container without rebuilding the image
apk add jpeg-dev zlib-dev freetype-dev lcms2-dev openjpeg-dev tiff-dev tk-dev tcl-dev
Well, you can use it happily. Others may be permission errors, or switch to the installation source
When running, there is an error: syntax error: ‘break’ outside loop
Reason: break can only be used in for and while loops
Specific examples of error reporting
>>> def func(L):
... result = {}
... if not isinstance(L,list):
... print("Incorrect type")
... break
...
File "<stdin>", line 5
SyntaxError: 'break' outside loop
Solution:
>>> def func(L):
... result = {}
... while not isinstance(L,list):
... print("Incorrect type")
... break
...
>>> func([1,2,3,4])
>>> func("qwe")
Incorrect type
I recently built a django + vue project platform. When I was a CV engineer last night, I encountered a bug and the information returned on the page was wrong.
The error message on the web page is as follows: Uncaught SyntaxError: Unexpected token<
Solution: In the data layer, the operation method of a database is wrong. The original method only needs to be displayed. Currently, it needs to be combined with VUE to realize the real-time display function of the search box. The original variable cannot be traversed, so an error is reported.
Code like this
Original code: hrefs = DB_hrefs.obiject.all()
After modification: hrefs = list(DB_hrefs.object.all().values())
The problem can be solved after the modification is completed.
1.error message: TypeError: Unicode-objects must be encoded before hashing
2.error message: TypeError: object supporting the buffer API required
The correct way to write it should be
codes:
import hashlib
def md5pwd(password):
m = hashlib.md5()
m.update(password)
mpwd = m.hexdigest()
return mpwd
print(md5pwd(b’123456′))
Python error: EOFError: Ran out of input
Error when running pickle-related functions: EOFError: Ran out of input
Previous code.
>>> import pickle >>> s = pickle.load(fp) Traceback (most recent call last): File "<stdin>", line 1, in <module> EOFError: Ran out of input
Cause analysis: to open a file in file operation mode
Solution:
Change to the following method
>>> fp = open("a.txt","rb+")
>>> import pickle
>>> s = pickle.load(fp)#Serialized Print Results
['apple', 'mango', 'carrot']
Error 1: ModuleNotFoundError: No module named ‘django.core.urlresolvers’
1 ModuleNotFoundError: No module named 'django.core.urlresolvers'
Solution: find the wrong file according to the prompt, and change all import django.core.urlresolvers to import django.urls

Error 2: TypeError: __init__() missing 1 required positional argument: ‘on_delete’
TypeError: __init__() missing 1 required positional argument: 'on_delete'

Error 3: typeerror:__init__() takes 1 positional argument but 6 were given
TypeError: __init__() takes 1 positional argument but 6 were given

change to
forms.Field.__init__(self)
forms.Field.__init__(self, required, widget, label, initial, help_text, *args, **kwargs) #change to forms.Field.__init__(self)
Error 4: ImportError: cannot import name ‘login’ from ‘django.contrib.auth.views’
