ipython profile create
#But an error is reported ImportError: No module named IPython

Try to install ipython, but:

pip install ipython

#But an error:

because the tmp folder is too big, check the folder size:

After trying to delete some files in the root directory, after deleting 20G, the problem is solved.

How to Solve ModuleNotFoundError: No module named ‘_bz2‘

When running pytorch code, “modulenotfoundererror: no module named” is reported_ Bz2 ‘”error, the complete error message is as follows:

ModuleNotFoundError: No module named '_bz2'

The reason for this error is that I use Python 3.7, but bz2 is installed in Python 3.6, so I can’t find it. In order to solve this problem, we need to copy the BZ Library in Python 3.6 to Python 3.7. The specific process is as follows:

1. Find the BZ library file in the path of python3.6, that is, the_ bz2.cpython-36m-x86_ 64-linux- gnu.so ”。

ls /usr/lib/python3.6/lib-dynload/

You can see that “- 36m” in the file name corresponds to Python 3.6.

2. Switch to the path corresponding to python3.7 and copy the file to the directory

cd /usr/local/lib/python3.7/lib-dynload

sudo cp /usr/lib/python3.6/lib-dynload/_bz2.cpython-36m-x86_64-linux-gnu.so ./

3. Modify the file name and change “- 36m” to “- 37m”

sudo mv _bz2.cpython-36m-x86_64-linux-gnu.so _bz2.cpython-37m-x86_64-linux-gnu.so

So far, the problem has been solved.

It should be noted that there is also a path/usr/lib/python3.7/lib-dynload. It is useless to copy the file to this directory. I need to copy it to the/usr/local/lib/python3.7/lib-dynload directory here.
