当我尝试运行import tensorflow_quantum时，我得到以下错误:
2021-08-19 11:03:01.024791: W tensorflow/stream_executor/platform/default/dso_loader.cc:64] Could not load dynamic library 'libcudart.so.11.0'; dlerror: libcudart.so.11.0: cannot open shared object file: No such file or directory

似乎有一些未定义的符号

但是我真的不知道这是什么意思。
我用的是Pop!_OS 21.04, Tensorflow 2.6.0, Tensorflow Quantum 0.6.0, python 3.9.5。我根据本页的说明安装了Tensorflow Quantum，但我仍然无法在python中导入它。当我尝试通过命令行或在Spyder或Jupyter笔记本中运行python时，我也会得到同样的错误。
我真的不知道这是怎么回事。我已经设法在这里找到了一些类似的问题/答案，但最有希望的只是链接到一个页面的说明，目前只是给出了一个404错误。如有任何帮助，我将不胜感激。
这个问题在TF 2.5、2.6中再次出现。在2.4.1中尝试，编辑代码:(请在python 3.7/3.8中尝试)
pip install -q tensorflow==2.4.1
pip install -q tensorflow-quantum
import tensorflow as tf
import tensorflow_quantum as tfq
