You are trying to decode an object that is already decoded. You have a str, there is no need to decode from UTF-8 anymore. Simply drop the .decode(‘utf-8’) part: As for your fetch() call, you are explicitly asking for just the first message. Use a range if you want to retrieve more messages. See the documentation: The message_set options to commands below is a … Read more
I’m using Windows, and I’m trying to install package cv2 for python3. I did a pip3 install opencv-python and it reports successful: But when I do the import cv2 from python3, it’s not found and I get weird errors: What am I doing wrong?
This error message means that you are attempting to use Python 3 to follow an example or run a program that uses the Python 2 print statement: The statement above does not work in Python 3. In Python 3 you need to add parentheses around the value to be printed: “SyntaxError: Missing parentheses in call to ‘print’” is … Read more
As you are in python3 , use dict.items() instead of dict.iteritems() iteritems() was removed in python3, so you can’t use this method anymore. Take a look at Python 3.0 Wiki Built-in Changes section, where it is stated: Removed dict.iteritems(), dict.iterkeys(), and dict.itervalues(). Instead: use dict.items(), dict.keys(), and dict.values() respectively.
You are trying to run a Python 2 codebase with Python 3. xrange() was renamed to range() in Python 3. Run the game with Python 2 instead. Don’t try to port it unless you know what you are doing, most likely there will be more problems beyond xrange() vs. range(). For the record, what you are seeing is not a syntax error … Read more
You open the file in text mode. More specifically: Good guesses for encoding is “ascii” and “utf8”. You can also leave the encoding off, and it will use the system default encoding, which tends to be UTF8, but may be something else.
You are just supposed to provide the predict method with the same 2D array, but with one value that you want to process (or more). In short, you can just replace With And it should work. EDIT: This answer became popular so I thought I’d add a little more explanation about ML. The short version: we can … Read more
Python tries to convert a byte-array (a bytes which it assumes to be a utf-8-encoded string) to a unicode string (str). This process of course is a decoding according to utf-8 rules. When it tries this, it encounters a byte sequence which is not allowed in utf-8-encoded strings (namely this 0xff at position 0). Since you did … Read more
I reckon the easiest/cleanest solution would be to use a tool that isolates your python environment, such as virtualenv Once installed, create a virtual env by specifying which version of python you want to use: $> virtualenv -p python3 env Note: puttin python3 directly works only for mac, with linux, you must specify the absolute path or your … Read more
You will need to update your LD_LIBRARY_PATH, so that it points to the /usr/local/cuda-9.0/lib64. Add the following line to your .bashrc file (or any other terminal you use)
