TypeError: The DType <class 'numpy.dtype[float64]'> could not be promoted by <class 'numpy.dtype[datetime64]'>. This means that no common DType exists for the given inputs. For example they cannot be stored in a single array unless the dtype is object

4. the gr.load() used to work just fine until Friday on this observation file, and other Rinex 2.11 obs. However, today I opened my project and I got the error above. I don't get the error while loading the corresponding nav file.
please use the following versions:
pandas == 0.25.3
numpy == 1.19.0
xarray == 0.12.1
Thank you, I was using differen versions. Although I've found that by enforcing the dtype to be 'object' for coord_type, I don't get that error anymore, and it doesn't seem to compromise the correct reading of the observations.

Hello, I am relatively new to numpy, how are you enforcing the dtype to be object?
Hi, if you're getting the same error, I think I did something of the kind:
try:
coord_dtype = np.result_type(self.coord_dtype, other.coord_dtype)
except:
coord_dtype = np.dtype('object') #here I am enforcing the type 'object' in case the result_type fails

I ended up using python 3.8 and the above 3 packages. it did work for loading rinex files.
