May I ask how is this going？

Getting a similar error with python=3.6, cuda=10.1, gcc=7.5.0

[oconnor127]

Had the same issue. What helped for me was to execute this command in my IDE (Pycharm) instead of the terminal.

How did you do？Could you show me your code in IDE(Pycharm)? Thank You!

[ymlili]

How to solute this problem?I've got the same.Please give some advice.Thank you so much!

You could try to install the ipython and then run the ipython by typing ipython. After than you should type:

run setup.py build_ext --inplace

That will also run the setup.py.
However that also did not solve the problem for me.
