Each version of pycocotools.whl file

Click any version in the link, (I installed 2.0.0), you must pay attention to the corresponding python version when downloading, cp36 refers to python3.6, cp37 and cp38 are the same.

After downloading, put it in your favorite folder, then start the command line, enter the directory where the whl file is located, and enter the following command. Note that install is followed by the full name of the whl file you downloaded

TypeError: expected str, bytes or os.PathLike object, not NoneType

Most of the problems occur because there is no specified path. The translation of the above problem is that a string or byte path is expected instead of the default value. If this problem occurs, you need to assign the variable of the specified path. This kind of error mostly occurs when running open source code.

Check the string variable at the corresponding position in the code, whether a certain value is passed in instead of None.
