I was not able to find a solution online, so I wanted to start a thread on this again.我无法在网上找到解决方案，所以我想再次启动一个线程。
UPDATE:更新：
I tried to uninstall matplotlib using conda/pip but it still shows up in conda list output:我尝试使用 conda/pip 卸载 matplotlib，但它仍然显示在 conda 列表输出中：

I came across this Error after reinstalling matplotlib twice after facing other Errors, which are:在遇到其他错误后，我两次重新安装 matplotlib 后遇到了这个错误，这些错误是：
ValueError: setting an array element with a sequence ValueError：使用序列设置数组元素
ValueError: 'transform' must be an instance of 'matplotlib.transform.Transform' ValueError：'transform' 必须是 'matplotlib.transform.Transform' 的一个实例
I was able to solve the above issues by reinstalling matplotlib using我能够通过使用重新安装matplotlib来解决上述问题
conda install -f matplotlib conda install -f matplotlib
But surprisingly I was able to solve this (ImportError: cannot import name 'rcParams' from 'matplotlib') just by restarting the Spyder(Python 3.7) from File Menu Restart option.但令人惊讶的是，我能够通过从文件菜单重新启动选项重新启动 Spyder（Python 3.7）来解决这个问题（ImportError: cannot import name 'rcParams' from 'matplotlib'）。
I restarted and the run the code, without any modifications code worked well.我重新启动并运行代码，没有任何修改代码运行良好。

I'm not certain if this corresponds to a recent change in how matplotlib works or if it was always so, but when I encountered the same error, it seemed that the issue was that rcParams cannot be directly imported with an import statement.我不确定这是否与matplotlib工作方式的最近变化相对应，或者是否始终如此，但是当我遇到相同的错误时，问题似乎是无法使用 import 语句直接导入rcParams 。 You must first import matplotlib , thus causing the module to be loaded into memory, cached, and possibly generate some dynamic objects.您必须首先导入matplotlib ，从而导致模块被加载到内存中、缓存并可能生成一些动态对象。 Then you can access rcParams .然后您可以访问rcParams 。
Case in point, this fails:举个例子，这失败了：
import matplotlib.rcParams as rcp
Traceback (most recent call last):
File "/home/nc/miniconda3/envs/pybnn/lib/python3.8/site-packages/IPython/core/interactiveshell.py", line 3417, in run_code
exec(code_obj, self.user_global_ns, self.user_ns)
File "<ipython-input-2-d4bca3da3c19>", line 1, in <module>
import matplotlib.rcParams as rcp
File "/snap/pycharm-community/211/plugins/python-ce/helpers/pydev/_pydev_bundle/pydev_import_hook.py", line 21, in do_import
module = self._system_import(name, *args, **kwargs)
ModuleNotFoundError: No module named 'matplotlib.rcParams'
However, this works:但是，这有效：
import matplotlib as mpl
rcp = mpl.rcParams
Backend Qt5Agg is interactive backend. Turning interactive mode on.

type(rcp)
Out[5]: matplotlib.RcParams
I'm using matplotlib 3.3.1 .我正在使用matplotlib 3.3.1 。

I was able to fix the issue above by first uninstalling and installing matplotlib.我能够通过首先卸载和安装 matplotlib 来解决上述问题。 Then completely creating a new notebook.然后完全创建一个新笔记本。 For some reason the old notebook still gave me the same error but when I create a new notebook in the same environment it worked, go figure.出于某种原因，旧笔记本仍然给了我同样的错误，但是当我在相同的环境中创建一个新的笔记本时，它可以工作，去图。

也许重命名您的select.py以避免名称冲突。
